How to optimally set up sublime text 3 for a beginner?

Question

JavaScript

Good afternoon! I recently started learning js. I use, as professionals advise, sublime text 3 to practice my skills, and with each new topic I encounter new problems in the sublime console. Tell me how to solve? Google doesn't turn up anything.
1. How to make Sublime Text 3 output dates to the console in the general format by default (like this: Sun Apr 08 2018 18:30:41 GMT + 0300 (Moscow time (winter)) taking into account local time, and not in ISO as it is now (2018-04-08T15:29:48.846Z)
2. When explicitly accessing the global object window gives an error:
var a = 5;
console.log( window.a );
ReferenceError: window is not defined
Is it possible to correct?
3. Is it possible to somehow display an alert in the sublime so that the browser does not need to go into the browser again?
I screwed the js console to the sublime in this way . And in general, tell me how best to optimally configure the js console for sublime 3 for a beginner so as not to once again be distracted by such things while studying? Or perhaps there is a friendlier editor for js development?

Answer 1

1) Remove sublime
2) Install vscode
