Can IntelliJ IDEA replace all other JetBrains IDEs at once?

Question

IntelliJ IDEA

I heard that IDEA with plugins completely replaces WebStorm, PhpStorm, PyCharm, Android Studio and other JetBrains IDEs. Is it so? Those. Will IDEA have, say, support for building a project through Grunt, support for Node.js and PHP frameworks, LiveReload, and all the other features from these development environments?

Answer 1

Is it so?

Yes

and all other features from these development environments?

Yes,
but you need to take into account that features first appear in EAP products (WebStorm, PhpStorm, PyCharm, Android Studio), then they get into products (WebStorm, PhpStorm, PyCharm, Android Studio), and then they come to IDEA plugins
