Get the item that appears the most times in an array

Question

var store = [\'1\',\'2\',\'2\',\'3\',\'4\'];

I want to find out that 2 appear the most in the array. How do I go about doing that?

Answer 1

If the array contains strings try this solution

    function GetMaxFrequency (array) {
    var store = array;
    var frequency = [];  // array of frequency.
    var result;   // holds the max frequency element.

    for(var v in store) {
        var target = store[v];
        var numOccurences = $.grep(store, function (elem) {
        return elem === target;
        }).length;
        frequency.push(numOccurences);

    }
    maxValue = Math.max.apply(this, frequency);
    result = store[$.inArray(maxValue,frequency)];
    return result;
}
var store = ['ff','cc','cc','ff','ff','ff','ff','ff','ff','yahya','yahya','cc','yahya'];
alert(GetMaxFrequency(store));
