I have a string
var str = '[SYSTEM, Test, check]'
I want to convert this String into array in order to access these values separately., like..
var array = ['SYSTEM', 'Test', 'check'];

You can do that by removing the beginning and end brackets and then splitting the string by ', '.
var array = str.replace(/\[|\]/g,'').split(', ');
This uses a regex to remove the brackets and than the split method to make the array
To elaborate a little more... I use /[|]/ to look for instances of [ and ]. I flag the regex as global (the g) in order to find all instances of it. Then I replace the instances with an empty string. Once all the instances have been removed, I split the string into an array based off of a comma and space seperator ', '
UPDATE:
As per the comments, you should check for the brackets at the beginning and end of the string, since we will assume you want brackets from any other values.
var array = str.replace(/(^\[|\]$)/g, '').split(', ');

I would even use anchors to avoid replacing brackets inside strings:
/^\[|\]$/

Nice, but that's better to check if brackets are the first and last characters :
str.replace(/^\[|\]$/g,'').split(', '). EDIT : I edited your answer (editception :) ).

@AnkitLamba developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/… would be helpful to look at. I tried to explain some in the paragraph right about "UPDATE"
var array = str.substring(1, str.length - 1).split(", ");
var str = '[SYSTEM, Test, check]'?
