A code editor gives developers an environment to write code using a specific programming language. While the code editor's primary purpose is to assist with coding, most of the editors go beyond and help developers with pointing errors, autocomplete suggestions, running the program, and other common areas of doubt.

We can install a code editor on our laptop or PC, or we can use an online version. This can help us avoid the hassle of installation, saving us both time and memory.

There are plenty of online programs to choose from, and in this article, we will explore 10 editors to help you with web programming.

Why do we need Online Code Editors?

Installing a code editor has several advantages, to be sure. But there are several factors that can make us choose an online version.

• Online code editors come with Zero configuration and Zero setup. You do not need to install, set up, or configure the editor at all. It's all there for you. You just need to start using it.
• They enable you to get started with some proofs-of-concept quickly.
• They allow you to create a sharable link for use elsewhere(maybe to embed in an article).
• You can collaborate and start pair-programming with other developers.
• You can Integrate with a source code repository like GitHub. This is an added benefit to keep your code up-to-date and use.

Ok, now we know the benefits, let's look at 10 online code editors to help with web development.

1. CodePen

CodePen Editor - Clean interface with compelling features

CodePen is a widely used online code editor to build and test front-end development. It allows you to create front-end projects (or Pens) using HTML, CSS, and JavaScript.

The segregated interfaces to write HTML, CSS, and JavaScript help developers focus on each of them at a time. You get to see the output as soon as you make any code changes.

There are plenty of utilities that make CodePen an easy choice for web developers. It allows you to share projects (pens) using URL. You can collect the relevant pens into Collections. You can view the trending pens, and follow them.

Another important aspect is that you can select preprocessors. For example, if you want to use programs like Sass or Less for CSS, or Babel for JavaScript, you can do that. Additionally, you can link to any JavaScript libraries like jQuery and import them to use in the CodePen.

This program is definitely worth a try, by the way: give it a shot if you haven't already.

2. StackBlitz

StackBlitz - Library, Framework, and Full-Stack

When you need a boilerplate (or starter project) using your favorite web development library, framework, you may want to try out StackBlitz. This online code editor goes beyond the regular HTML, CSS, and JavaScript-based project support. You can create projects using React, Angular, Vue, Sveltes, and many others.

StackBlitz has the support of TypeScript-based starter projects. You can also create projects with plain old JavaScript or just with HTML5. You can also sign up for beta access to the full-stack projects.

A big plus of StackBlitz is its integration with GitHub. With the free plan, you can connect to any public GitHub repository and work on the source code. The NPM dependency management is another great support provided out-of-the-box.

3. CodeSandBox

CodeSandBox - An all-rounder code editor

CodeSandBox is an online code editor and prototyping tool that helps with web development. Like StackBlitz, it also supports project structure creation using web development libraries, frameworks. You can connect to GitHub projects and edit them using CodeSandBox. Other benefits include NPM library management, enabling you to link to any external library on CDN, and a feature that allows you to add a new font.

Two unique features make CodeSandBox an excellent code editor to use:

• Deployment: You can deploy a production version of your app from CodeSandbox to some well-known providers like Netlify, Vercel, and GitHub Pages.
• Live: You can collaborate with other developers in real-time by inviting them to edit the code along with you.

4. JSFiddle
