Using JavaScript it is possible to split string with Symbol.split (with splitter) in following way.

1. Split string with Symbol.split method (with splitter) example

// ONLINE-RUNNER:browser;

var splitter = {
    [Symbol.split] : function(text, limit) { // this function splits string by space
        let result = [ ];

        if (text.length > 0) {
            let index = 0;
            for (let i = 0; i < text.length; ++i) {
                if(text[i] == ' ') {
                    result.push(text.substring(index, i));
                    index = i + 1;


        return result;

// Example:

var text = 'This is some text...';
var array = text.split(splitter);


Output (with NodeJS):

[ 'This', 'is', 'some', 'text...' ]

Note: Symbol.split has been introduced in ES2015.
