Description
Prefer using explicit casts by calling Number, Boolean, or String over using operators like +, !! or "" +.
This is considered best practice as it improves readability.
Bad Practice
const b = !!foo;
// The `+` operator does not change the value of its operand
// unless it's already a number.
let n = +foo;
n = 1 * foo;
const s = "" + foo;
Recommended
const b = Boolean(foo);
const n = Number(foo);
const s = String(foo);
