Tests:

bind
function fn1() { return 1 + 1; } function fn2() { return 2 + 2; } function fn3() { return 3 + 3; } function fn4() { return 4 + 4; } function createSomething() { return [fn1.bind(), fn2.bind(), fn3.bind(), fn4.bind()] } for (let i = 0; i < 100; i++) { let [a, b, c, d] = createSomething(); for (let j = 0; j < 100; j++) { a(); b(); c(); d(); } }
closure
function createSomething() { function fn1() { return 1 + 1; } function fn2() { return 2 + 2; } function fn3() { return 3 + 3; } function fn4() { return 4 + 4; } return [() => fn1(), () => fn2(), () => fn3(), () => fn4()] } for (let i = 0; i < 100; i++) { let [a, b, c, d] = createSomething(); for (let j = 0; j < 100; j++) { a(); b(); c(); d(); } }
