Some coding challenges for the AO front end team who are learning JavaScript

Write a Jasmine like API for a global Assert function

// with three methods toBe, toBeExactly and toBeTypeof
function Assert(val) {
    return {
        toBe : function(expected) {
            return val == expected;
        },
        toBeExactly : function(expected) {
            return val === expected;
        },
        toBeTypeof : function(expected) {
            return typeof val === expected;
        }
    };
};

function Assert(val) {
    Assert.val = val;
    return Assert;
}

Assert.toBe = function(expected) {
    return this.val == expected;  
};

Assert.toExactlyBe = function(expected) {
    return this.val === expected;  
};

Assert.toBeA = function(expected) {
    return typeof this.val === expected;  
};

var assert = {};
assert.expect = function(val){
    this.val = val;
};
assert.toBe = function(expected) {
    return this.val === expected;
};

Assert("1").toBe(1);
assert.expect("1").toBe(1);
