Wait for an element to exist on the page with jQuery

wait-el.js

// altered to version like described in comments and passing back selector
// to be used later with that or whatever var one chooses
// maxTimes should be used to not have a neverending timeout loop
const waitForEl = (selector, maxTimes = false, callback) => {
    // wait for selector until it exists and pass it back
    if (jQuery(selector).length) {
        callback(selector);
    } else {
        if (maxTimes === false || maxTimes > 0) {
            (maxTimes != false) && maxTimes-- ;
            setTimeout(function () {
                waitForEl(selector, maxTimes, callback);
            }, 100);
        }
    }
};    

waitForEl(selector, maxTimes, (that)=>{});
