One is its HTTP Inspector, which is excellent for debugging Ajax callbacks. Komodo IDE has several features that most competing products lack. On the performance side, Komodo’s speed has improved noticeably compared to older versions, with faster screen drawing, search, and syntax checking. If we’re comparing tools, Komodo is more of an IDE, while Sublime Text is much faster. Komodo also has both column editing and multiple selections, providing near parity with Sublime Text and TextMate for mass edits. Nevertheless, these are some of the most useful cases. Unfortunately, the “least common denominator” nature of this approach limits Komodo's capabilities to renaming variables and class members, and to extracting code into a method.

The IDE has a code refactoring module for all of the languages for which it provides code intelligence: PHP, Perl, Python, Ruby, Tcl, JavaScript, and Node.js. Komodo IDE is a very good choice for end-to-end development in open source languages. Komodo supports dozens of programming and markup languages, and offers a wide range of support, including refactoring, debugging, and profiling. For that, you can always run JSHint in a shell. Komodo IDE provides advanced JavaScript editing, syntax highlighting, navigation, and debugging, but it doesn’t include JavaScript code checking.

Although newer products such as Visual Studio Code and WebStorm have surpassed it in some areas, it is still a good editor and IDE. I have been a user and fan of Komodo IDE since it was first introduced in 2001. With some effort, you can make Eclipse work with Angular and React projects it just depends on how you define 'work.' I'd consider switching to another tool for these languages and frameworks, for example Visual Studio Code, unless you absolutely must work inside of Eclipse. The plugins for Angular, TypeScript, and React have been updated more often than the Web Tools Platform as of this writing, Wild Web Developer and CodeMix seem to be the best options, although several reviewers in the Eclipse Marketplace criticize each of them as less than optimal. In other words, it has changed little in three years.Įclipse has always enjoyed a huge marketplace of plugins. Eclipse 2018 with JavaScript Development Tools had a half-decent plain JavaScript editor and a Chrome-based debugger, but it didn't know about TypeScript, which is used by Angular, or about ES6 (ECMAScript 2015) and JSX files, which are used by React.Įclipse 2021 with Web Tools Platform 3.23 includes JSDT 2.x, and supports ES6 Node.js and tools like npm, Bower, Gulp and Grunt and Chromium debugging. When I tried using Eclipse Luna with JSDT for JavaScript development in 2014, it constantly displayed false-positive errors for valid code that passed JSHint.įortunately, several vendors and open source projects have stepped up to the plate since then. Ten-plus years ago, when I did some Android development with Eclipse, I found the experience okay, but poky. Eclipse 2021 with JavaScript Development Toolsīack in the ancient days when Java Swing was new and exciting, I enjoyed using Eclipse for Java development, but soon moved on to other Java IDEs. But as more editors add hooks to these systems, ALM support is becoming less of a differentiator. IDEs also have support for application lifecycle management (ALM) systems, integrating with the likes of Git, GitHub, Mercurial, Subversion, and Perforce for version control. Why use an IDE instead of an editor? The main reason is that an IDE can debug and sometimes profile your code.

Fortunately, JavaScript development tools-both editors and IDEs-are rising to meet the new challenges.

But JavaScript also helps build mobile applications, and it has found an important place on the back end in the form of Node.js servers. Most often, it works with HTML5 and CSS to build web front ends. JavaScript is used for many different kinds of applications today.
