Javascript:绑定(bind)到函数的右侧？

Question

如何绑定(bind)到函数的右边？示例:

var square = Math.pow.bindRight(2);
console.log(square(3)); //desired output: 9

Answer 1

Function.prototype.bindRight = function() {
    var self = this, args = [].slice.call( arguments );
    return function() {
        return self.apply( this, [].slice.call( arguments ).concat( args ) );
    };
};

var square = Math.pow.bindRight(2);
square(3); //9
