jquery arrays comparison with substrings and case insensitive

Folks I have a jquery function requirement that will compare two arrays.

listA = [' APPLE', 'banana', 'orange'] listB = [ 'BANANA ','appl']

ok so in above example, I need function to return "true". Basically what I need is a way to

my code so far

<script>

$(document).ready(function(){
Array.prototype.contains = function(array) {
return array.every(function(item) {

    array = $.map(this, function(value){
       return value.replace(/ /g, '').toUpperCase();
    });

    return array.indexOf(item.replace(/ /g, '').toUpperCase()) >= 0;
}, this);
}

var result = [' APPLE', 'banana ', 'orange'].contains([ ' BANANA',' Appl ']);
alert(result);

});

so in above code example, it should return "true"

Any help is much appreciated

You can update the Array.prototype.contains function as below, this will remove the leading and trailing spaces and use a case insensitive comparison under the map function:

Array.prototype.contains = function(array) {
    return array.every(function(item) {
        var searchResult = this.map(function(i) {
            return i.trim().toLowerCase().indexOf(item.trim().toLowerCase()) >= 0;
        });

        return searchResult.includes(true);
    }, this);
}

You can use toUpperCase() or toLowerCase() methods when doing the comparison.

for example:

let areEqual = str1.toUpperCase() === str2.toUpperCase();

Instead of return within array.every( .. )

use a counter. Then ..

return counter == array.length
