[removed] How to create an Object and filter on those attributes? [duplicate]

Answer 1

Array.prototype.select = function(filter) {

    if (!filter) return this;

    var result = [], item = null;
    for (var i = 0; i < this.length; i++) {
        item = this[i];
        if (filter(item)) {
            result.push(item);
        }
    }

    return result;
}

function filterHomes(homes) {
    var a = 1, b = 2, c = 3, x = 4, y = 5, z = 6;
    return homes.select(function(item) {
        return between(item.price, x, y) && item.num_of_baths >= z && inArray(item.num_of_beds, [a, b, c]);
    });
}

function between(value, min, max) {
    return value >= min && value <= max;
}

function inArray(value, values) {
    for (var i = 0; i < values.length; i++) {
        if (value === values[i]) return true;
    }
    return false;
}
