What is function currying in javascript?
Creating a copy of a function but with some preset parameters (very useful in mathematical situations).

<p id="demo"></p>

After that add this JS code.

JS

function multiply(a, b){
    document.getElementById('demo').innerHTML = a * b;
}

var multipleByTwo = multiply.bind(this, 2);
multipleByTwo(4);
