I am using find () function
for one of my project. Official document https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/find says that Internet Explorer is not supported. What else can I use?

A polyfill is a code that provides the functionality that you normally expect the browser to provide you natively. Here is the polyfill for Array.find
if (!Array.prototype.find) { Array.prototype.find = function(predicate) { if (this === null) { throw new TypeError('Array.prototype.find called on null or undefined'); } if (typeof predicate !== 'function') { throw new TypeError('predicate must be a function'); } var list = Object(this); var length = list.length >>> 0; var thisArg = arguments[1]; var value; for (var i = 0; i < length; i++) { value = list[i]; if (predicate.call(thisArg, value, i, list)) { return value; } } return undefined; }; }
