Script Preparation code:

function double(n) {
	return n*2;
}
var data = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30];

Tests:

Ramda.map
R.pipe( R.add(5), R.subtract(3), R.multiply(10), R.divide(2) )(0)
Array.prototype.map
const t = ((0 + 5 - 3) * 10) / 2
lodash.map
_.map(data, double);
Immutable.map
Immutable.fromJS(data).map(double)
