Here is a really simple implementation of an assert function. It takes a value and a description of what you are testing.

 function assert(value, description) {
        var result = value ? "pass" : "fail";
        console.log(result + ' - ' +  description); 
    };

If the value evaluates to true it passes.

assert (1===1, 'testing if 1=1');  

If it returns false it fails.

assert (1===2, 'testing if 1=1');
