Programming languages are developers’ tools—and each is well suited for a particular kind of website, application type, or project size and scope. Developers will have their preferences, and will also know which languages and frameworks to use to maximize an application’s potential as well as its efficiency.

However, when it comes to these skills—probably the most overwhelming aspect for a non-technical person to sift through—frameworks and languages are often front and center on developers’ resumes. That’s why we’ve compiled a quick look at the most popular programming languages and frameworks, so you can hire faster and more effectively.

The programming language landscape

There’s a great deal of overlap in web development—fluid teams don’t work in silos. They’re versed in multiple technologies and know when and where to apply these skills to your project. The same goes for development languages—there’s a lot of repurposing and layering.

Your developer will know which language or framework to use and when. What you should know before you begin choosing software and languages is what these tools can do and when they’re best put to work. In certain situations, a streamlined approach to picking software will work, like choosing a time-tested software stack, but other times, you’ll want to layer in languages and frameworks to address certain layers of your application.

Hiring based on a language won’t always be your focus, but having a core understanding of the following will make finding the perfect developer that much easier.

Languages for every part of your site: Markup languages, Client-side scripts, and Server-side scripts

Which area of development do you need support for? Client-side scripting creates what users interact with on your site; server-side scripting is typically your site’s back-end development; database technology manages all the information on the server that supports a website; markup languages are the backbone of it all.

A quick website breakdown

Site markup: HTML, CSS, and XML organize, style, and house the content of your site. Scripts and CSS files are embedded into the HTML file and interact with the HTML elements to create an interactive site.
Client-side scripting: This code runs in a web browser and determines what your customers or clients will see when they land on your website. It gives a site functionality—anything from drop-down menus to animation.
Server-side scripting: This code executes on a web server and powers the behind-the-scenes mechanics of how a website works. It builds a site’s architecture and serves as a go-between with the database.
Database technology: It stores all the site data that are requested, retrieved, and edited via scripts. It helps keep a website running smoothly and requires management and maintenance as a site evolves.

Markup languages and style sheets

Basic languages like HTML and cascading style sheets (CSS) are the building blocks of most sites—the structure, organization, and look and feel. HTML5 is the latest version, with advantages like more cross-platform compatibility and fewer errors. XML and JavaScript Object Notation (JSON) are data exchange formats.

XHTML

Client-side scripting languages & frameworks

Other languages are used specifically for client-side scripting—namely, JavaScript. These scripts are embedded in the HTML markup and transform your website from a static page to a hard-working, interactive application. Client-side code runs in the browser—it’s temporarily downloaded from the server to the browser so it can run independently of the server. Client-side scripts have several frameworks to support developers and add extra functionality. What your site gets from these scripts is a fast, seamless, desktop experience, with less load on the server. To keep pace with these more advanced dynamic websites, there are also CSS preprocessors and front-end frameworks that make it easier to style your websites and keep pace with the ever-evolving world of web design.

Browser-based, front-end languages include:

JavaScript
ActionScript
VBScript
Silverlight (for gaming)

Popular client-side frameworks and libraries include:

jQuery
AngularJS, Angular 2
Aurelia
Backbone.js
Ember
Knockout.js
Mercury.js
Meteor.js
Polymer
React
Underscore
Vue

Popular CSS pre-processors and front-end frameworks include:

LESS
Sass
Bootstrap
Foundation
Gumby
Material UI
materializecss
Pure
Semantic UI
Susy
CoffeeScript, a compile-to-JavaScript language, and TypeScript, a Microsoft JavaScript superset

Server-side scripting languages & frameworks

All sites are hosted on a powerful computer called a server. Without getting too technical, server-side code lives on your server and has direct access to your database. By running on the server, it serves as a go-between architecture, transferring data to the browser, minimizing the browser’s workload (and necessary client-side scripting), and making your site more secure.

Each language has several frameworks to support developers in writing code—some with add-ons, extras, and built-in APIs and other software that make building a top-to-bottom application fast and easy.

Server-Side Scripting Languages:

PHP
C#
C, C++ languages
Java language
Scala language
ColdFusion language
Ruby programming language
Perl & Perl 5
Python
JavaScript via Node.js
Erlang
SQL, a language for database queries

Popular server-side frameworks and libraries include

ASP.NET framework
Node.js
The Ruby on Rails framework
The Django framework (Python)
Laravel, CakePHP

Patient safety assistant

Check your symptom safely

Hi, I am RX Symptom Navigator. I can help you understand what to read next and what warning signs need care.

Warning: Do not use this in emergencies, pregnancy, severe illness, or as a substitute for a doctor. For children or teens, use with a parent/guardian and clinician.

A rural-friendly guide: warning signs, when to see a doctor, related articles, tests to discuss, and OTC safety education.

1 Symptom 2 Severity 3 Safe guidance

First safety question

Is there chest pain, breathing trouble, fainting, confusion, severe bleeding, stroke-like weakness, severe injury, or pregnancy danger sign?

Choose quickly

All symptoms

Browse by body area

Start here: Write or select a symptom. The guide will show warning signs, doctor guidance, diagnostic tests to discuss, OTC safety education, and related RX articles.

Important: This tool is educational only. It cannot diagnose, treat, or replace a doctor. OTC information is not a prescription. In an emergency, contact local emergency services or go to the nearest hospital.

Safety note: This is not a prescription or diagnosis. For severe symptoms, pregnancy danger signs, children with serious illness, chest pain, breathing difficulty, stroke-like weakness, or major injury, seek urgent care.

Which doctor may help?

Start with a registered doctor or the nearest qualified health center.

What to tell the doctor

Write when the problem started and how it changed.
Bring old prescriptions, investigation reports, and current medicines.
Write allergies, pregnancy status, diabetes, kidney/liver disease, and major past illnesses.
Bring one family member if the patient is weak, elderly, confused, or a child.

Questions to ask

What is the most likely cause of my symptoms?
Which danger signs mean I should go to hospital quickly?
Which tests are necessary now, and which can wait?
How should I take medicines safely and what side effects should I watch for?
When should I come for follow-up?

Tests to discuss

Vital signs: temperature, pulse, blood pressure, oxygen saturation
Basic physical examination by a clinician
CBC, urine test, blood sugar, or imaging only when clinically needed

Avoid these mistakes

Do not use antibiotics, steroid tablets/injections, or strong painkillers without proper medical advice.
Do not hide pregnancy, kidney disease, ulcer, allergy, or blood thinner use.
Do not delay emergency care when danger signs are present.

Medicine safety and first-aid guide

This section is for patient education only. It does not replace a doctor, pharmacist, or emergency care.

Safe first steps

Rest, drink safe water, and observe symptoms carefully.
Keep a written note of symptoms, duration, temperature, medicines already taken, and allergy history.
Seek medical care quickly if symptoms are severe, worsening, or unusual for the patient.

OTC medicine safety

For mild pain or fever, ask a registered pharmacist or doctor before using common over-the-counter pain/fever medicines.
Do not combine multiple pain medicines without advice, especially if you have kidney disease, liver disease, stomach ulcer, asthma, pregnancy, or take blood thinners.
Do not give adult medicines to children unless a qualified clinician advises it.

Avoid these mistakes

Do not start antibiotics without a proper medical decision.
Do not use steroid tablets or injections casually for quick relief.
Do not delay emergency care because of home remedies.

Get urgent help if

Severe symptoms, confusion, fainting, breathing difficulty, chest pain, severe dehydration, or sudden weakness need urgent medical care.

Medicine names, dose, and timing must be decided by a qualified clinician or pharmacist after checking age, pregnancy, allergy, other diseases, and current medicines.

For rural patients and family caregivers

Patient health record and symptom diary

Write your symptoms, medicines already taken, test results, and questions before visiting a doctor. This note stays on your device unless you print or copy it.

Doctor to discuss: Doctor / qualified healthcare provider

Tests to discuss with doctor

Basic vital signs: temperature, pulse, blood pressure, oxygen level if needed
Relevant blood, urine, imaging, or specialist tests only after clinical assessment

Questions to ask

What is the most likely cause of my symptoms?
Which warning signs mean I should go to emergency care?
Which tests are really needed now?
Which medicines are safe for my age, pregnancy status, allergy, kidney/liver/stomach condition, and current medicines?

Emergency warning signs such as chest pain, severe breathing difficulty, sudden weakness, confusion, severe dehydration, major injury, or loss of bladder/bowel control need urgent medical care. Do not wait for online information.

Go to emergency care if you notice:

Severe or rapidly worsening symptoms
Breathing difficulty, chest pain, fainting, confusion, severe weakness, major injury, or severe dehydration

Doctor / service to discuss: Qualified healthcare provider; specialist depends on symptoms and examination.

Step 1
Check danger signs first
If danger signs are present, seek emergency care and do not wait for online information.
Step 2
Record the symptom story
Write when symptoms started, severity, medicines already taken, allergies, pregnancy status, and test results.
Step 3
Visit a qualified clinician
A doctor, nurse, or qualified healthcare provider can examine you and decide which tests or treatment are needed.
Step 4
Do only useful tests
Do tests after clinical assessment. Avoid unnecessary tests, random antibiotics, or repeated medicines without diagnosis.
Step 5
Follow up and return early if worse
If symptoms worsen, new warning signs appear, or treatment is not helping, return for review quickly.

Rural patient practical tips

Take a written symptom diary and all previous prescriptions/test reports.
Do not hide medicines already taken, even herbal or over-the-counter medicines.
Ask which warning signs mean urgent referral to hospital.

This roadmap is for education. A real diagnosis and treatment plan requires history, examination, and clinical judgment.
