What is the difference between call and apply? 19 answers

Apply takes a single array of arguments, useful for method chaining, the javascript equivalent of calling super. in Java etc.

function makeNoise() {
   Foo.prototype.makeNoise.apply(this, arguments);
}

Call takes list of parameters, more useful other situations where the arguments are only available as single variables.

fn.call(this, x, y, z);

which would just be shorthand for

fn.apply(this, [x, y, z])

Given you have an array of arguments you need to use apply()
