Object Comparing: check if an object contains the whole other object

Question

I have two objects. Their structure looks a bit like this:

{
 education: [\"school\", \"institute\"],
 courses: [\"HTML\", \"JS\", \"CSS\"],
 Computer: {
            


        

Answer 1

Just recursively check it:

function isContainedIn(a, b) {
    if (typeof a != typeof b)
        return false;
    if (Array.isArray(a) && Array.isArray(b)) {
        // assuming same order at least
        for (var i=0, j=0, la=a.length, lb=b.length; i

> isContainedIn(requirements, person)
true

For a more set-logic-like approach to arrays, where order does not matter, add something like

        a.sort();
        b = b.slice().sort()

(assuming orderable contents) before the array comparison loop or replace that by the quite inefficient

        return a.every(function(ael) {
            return b.some(function(bel) {
                return isContainedIn(ael, bel);
            });
        });
