Question

What is the best method of searching through an array for individual characters and returning true if found and false if not using JS?

For example:

search["adipisci","adipiscix"] 

returns false in array element 1 and true in array element 2 when “sciipx” is searched

Many thanks!

The following should do the trick:

var search = "sciipx".split('');
var elems = ["adipisci","adipiscix"];
var matches = [];

for (var i = 0; i < elems.length; i++) {
    var found = true;
    for (var j = 0; j < search.length; j++) {
        if (elems[i].indexOf(search[j]) < 0) {
            found = false;
            break;
        }
    }
    if (found) {
        matches.push(i); // you can do elems[i] if you prefer
    }
}

In the end matches will be an array with indexes of strings that matched.

NB: If you need it, the loops can be further optimized.
