I&#x27;ve only used three different IDEs&#x2F;editors with regularity: Eclipse, IntelliJ and Sublime Text. I&#x27;ve dabbled with others like Atom and Brackets, and you&#x27;re right, they all seem to have a bit of &quot;heft&quot; to them - except for Sublime Text. It starts up quickly. It&#x27;s closes quickly. It&#x27;s always immediately responsive. What makes it different from the others?
