Hi All,

If you tried to use find or findIndex in your server-side suitescript code and came up short, ie got an error like “TypeError: Cannot find function find in object ” or “TypeError: Cannot find function findIndex in object ” I’ll show you how to fix this and add modern array functionality to NetSuite’s server-side javascript engine.

Just add this function to your script or library and call it:

Code:
//fix netsuite javascript engine
//adds modern array functionality
function FixNetSuiteJavaScript() {
// https://tc39.github.io/ecma262/#sec-array.prototype.find
if (!Array.prototype.find) {
Object.defineProperty(Array.prototype, ‘find’, {
value: function (predicate) {
// 1. Let O be ? ToObject(this value).
if (this == null) {
throw new TypeError(‘”this” is null or not defined’);
}

var o = Object(this);

// 2. Let len be ? ToLength(? Get(O, “length”)).
var len = o.length >>> 0;

// 3. If IsCallable(predicate) is false, throw a TypeError exception.
if (typeof predicate !== ‘function’) {
throw new TypeError(‘predicate must be a function’);
}

// 4. If thisArg was supplied, let T be thisArg; else let T be undefined.
var thisArg = arguments[1];

// 5. Let k be 0.
var k = 0;

// 6. Repeat, while k >> 0;

// 3. If IsCallable(predicate) is false, throw a TypeError exception.
if (typeof predicate !== ‘function’) {
throw new TypeError(‘predicate must be a function’);
}

// 4. If thisArg was supplied, let T be thisArg; else let T be undefined.
var thisArg = arguments[1];

// 5. Let k be 0.
var k = 0;

// 6. Repeat, while k This is a cached copy. Click here to see the original post.
