JavaScript: Case Insenstive Array Search

Question

I have a case like,

var givenTerms = [Tree, Plant, River, Ocean, Place, Sky];
var check = 'SKY';
if ($.inArray(check, givenTerms()) !== -1) {
    // say it is present in givenTerms
}

This case fails as it is case sensitive. I could not use givenTerms.toLowercase() as it is an array and not a single term. Is there any other possibility to make this if case true.

Any suggestion could be helpful.

Always have constant array in lower case and compare it with the same case... — Rayon, Mar 30 '17 at 10:01

First you need to update/Create a new array for matching string. Here I update the original collection that match search term. Check the result here

var givenTerms = [Tree, Plant, River, Ocean, Place, Sky];
var check = 'SKY';  
givenTerms = ((givenTerms.toString()).toUpperCase()).split(",");
if (givenTerms.indexOf(check) >= 0) {
    alert(check +" found at "+ givenTerms.indexOf(check));
}
