I have a string like this :
var str = "[x] + [y] - [z]"
I want an array:
arr[0] = x , arr[1]=y ...and so on.
My string can contain multiple operators and fields

You can write a regex to replace the arithmatic operations and '['. Then split the string by ']' to get an array.
PS: slice(0, -1) is remove the last item from the array which is just a "".
var str = "[x] + [y] - [z]";
var arr = str.replace(/[+-/*//[ ]/g,'').split("]").slice(0, -1);;
console.log(arr)5 Comments

i have a string like this "[numA1-E1]+[SalineLotNumberQ2-P1]" . The regex gives arr[0] = numA1E1 whereas i want arr[0] = numA1-E1. If you can help out on this?

Cant create that. It will be the same question. I just want the minus sign to be not removed when it is in a [ ].
