IntelliJ IDEA vs Eclipse with JSDT

IDEA places an emphasis in safe refactoring, offering a variety of features to make this possible for a variety of languages.
These features include safe delete, type migration and replacing method code duplicates.

Uses a fast indexing technique to provide contextual hints (auto-completion, available object members, import suggestions).
On-the-fly code analysis to detect errors and propose refactorization.

A very complete development environment support.

IntelliJ supports many languages besides Java, some of these are: golang, Scala, Clojure, Groovy, Bash, etc.

Many plugins are available for almost any task a developer may need to cover. Plugins are developed by Jetbrains themselves or by 3rd parties through the SDK available for writing them.

IntelliJ IDEA hardly ever crashes or has any issues that plague other Java IDEs like file corruption or slowness.

IDEA has a clean, intuitive interface with some customization available (such as the Darcula theme).

The documentation is exhaustive, easy to navigate, and clearly worded.

With ability to step into a certain part of a large method invocation (Shift+F7), drop frame, executing code snippets, showing method return values, etc.

There is a free community edition (open source) and an ultimate edition, which you can compare here.

The ultimate edition is available for free for one year for students but must be registered through an .edu e-mail account.

These simplify the daily work, e.g. copy/cut a whole line without the need to select it.

Verify yourselves as a student to get more perks.

Creating an embedded database, running SQL script in a dedicated terminal, viewing tables and their contents, and creating a connection to an in-memory or embedded database is fully supported.

I pay $24 a month and i have access to all jetbrain peoducts , so i use their many tools , i tried many others like netbeans , eclipse , etc , they re good but intelij is on the space and the sky is the limit . Been using it for 5 years and i cant tell i got frustrated using .it

Eclipse with JSDT provides you with quick fixes every time a warning or error is raised by the IDE. This feature is particularly helpful at places in code where errors were caused by the programmer just being a little "lazy", such as missing out the + sign between two operands or a variable being out of scope.

Just like all other IDEs, Eclipse offers you inline code completion (even with any external JS libraries added to the project).

Eclipse runs on Windows, Linux and Mac, and is totally free of cost.

Eclipse's refactoring features are quite similar to Webstorm's. It provides almost the same functionalities which include renaming, moving, and member extraction to make your code tidier

This feature is particularly useful when you've added a lot of nesting in your code and you're unable to recall which opening bracket corresponds to which closing one.

Eclipse has a large and active community, which has resulted in a wide variety of plugins.

Thanks to the large variety of plugins and various configuration options available, Eclipse is very customizable.

Eclipse lets you integrate web servers (like Apache or Jetty) into the IDE, which you could use for in-container testing or providing services.

Pulling, pushing, staging, stashing, etc., are all available in Eclipse as IDE functionalities.
