Best way to find if an item is in a JavaScript array?

Question

Can anyone help me help me what is the best way to find if the object is in an array or not in JavaScript?

Answer 1

Basically, you can use includes() function to find:

arr.includes(obj);

Also, for other older browsers, you can try the below code:

function include(arr,obj) {

    return (arr.indexOf(obj) != -1);

}

I hope this will help.
