Remove useless if in js example

If the length is 0, then the forEach call does nothing anyway

Could we remove the slice part as well ? If IE support is required, can’t we just use Array.prototype.forEach ? Can’t we just remove IE support all together to promote clean and up to date code ? Polyfills and code transpilation are here to help support IE
