Javascript – How can I split a string with an exact match of a variable?

Basically, I need to split a string to remove any exact matches.

Here’s what I tried.

let str = 'a abc a a bac';
let m = 'a';
str.split(m);

the result will remove all occurrences of the variable in the str. I need a way to put a variable inside a /^$/ regex to get only the exact matches. Any suggestions ?

    It sounds like you want to split your input into "words", then filter out some of the words. This can be achieved by using split followed by filter:

    const str = 'a abc a a bac';
const m = 'a';
const result = str.split(/s+/).filter(x => x != m);
console.log(result);

    let str = 'a abc a a bac';
//as you asked a to be in variable
let m = 'a';
//we need to form RegEx with variable
//this expression matches a with word boundry and spaces if you wish to keep spaces just remove |\s 
let reg = new RegExp('\b' + m + '\b|\s/gm')
console.log(str.split(reg))
