/**
 * Create a bound function.
 * 
 * @param  {Function} func      - The function to be bound.
 * @param  {Array}    args      - The function arguments.
 * @param  {*}        [context] - The function context.

function bind(func, args, context) {
    return func.apply(context, args);
}

// test
function logX(a) {
    console.log(this.x + a);
}

var obj1 = { x: 1 };
var obj2 = { x: 2 };

bind(logX, ['foo'], obj1); // 1foo
bind(logX, ['bar'], obj2); // 2bar
