JavaScript is used for many different kinds of applications today. Most often, it works with HTML5 and CSS to build web front ends. 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. Fortunately, JavaScript development tools—both editors and IDEs—are rising to meet the new challenges.Why use an IDE instead of an editor? The main reason is that an IDE can debug and sometimes profile your code. IDEs also have support for application lifecycle management (ALM) systems, integrating with the likes of Git, GitHub, Mercurial, Subversion, and Perforce for version control. But as more editors add hooks to these systems, ALM support is becoming less of a differentiator.Eclipse 2021 with JavaScript Development ToolsBack 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. Ten-plus years ago, when I did some Android development with Eclipse, I found the experience okay, but poky. 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.
