How to split words using javascript

Question

This might be a simple question but, how do i split words... for example

a = "even, test"

I have used .split to seperate the text with space.

so the result came is like

a = "even,"
b = "test"

But, how do I remove the 'comma' here?

But in some conditions it might get "even test" and in some conditions i might get "even, test". All are dynamic, so how do i check it for both?

Thanks

I found a list of word separators in Sublime Text default settings. Here's how to split with it, with some Unicode support (the defined separators are not Unicode though):

{ // word_separators: ./\()"'-,;<>~!@#$%^&*|+=[]{}`~?: (32)
    function splitByWords(str = '', limit = undefined) {
        return str.split(/[-./\\()"',;<>~!@#$%^&*|+=[\]{}`~?:]/u, limit)
    }

    function reverseString(str) {
        let newString = ''
        for (let i = str.length - 1; i >= 0; i--)
            newString += str[i]
        return newString
    }

    const str = '123.x/x\\x(x)x"x\'x-x:x,789;x<x>x~x!x@x#x$x%x^x&x*x|x+x=x[x]x{x}x`x~x?456'
    console.log(splitByWords(str)) // (33) ["123", "x", "x", "x", "x", "x", "x", "x", "x", "x", "789", "x", "x", "x", "x", "x", "x", "x", "x", "x", "x", "x", "x", "x", "x", "x", "x", "x", "x", "x", "x", "x", "456"]
    console.log(splitByWords(str, 1)) // ["123"]
    console.log(splitByWords(reverseString(str), 1)) // ["654"]
}

For some reason the - has to be at the beginning, and the : at the end. Edit: you might want to add \s (after the -) to count whitespace as separator
