Benchmark: Convert boolean to number

Script Preparation code:

const arr = Array.from({ length: 100000 }, () => Math.random() > 0.5);

Tests:

+
const converted = arr.map(v => +v);
Number call
const converted = arr.map(v => Number(v));
? :
const converted = arr.map(v => v ? 1 : 0);
if
const converted = arr.map(v => { if (v) return 1; else return 0; });
Number
const converted = arr.map(Number);
