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;
                }
            }

            result.push(text.substring(index));
        }

        return result;
    }
};

// Example:

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

console.log(array);

Output (with NodeJS):

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

Note: Symbol.split has been introduced in ES2015.
