Answer 1

If you are using floating numbers and if they are computed ones. Below will be a slightly more reliable way.

console.log(Number(0.1 + 0.2) == Number(0.3)); // This will return false.

To reliably/almost reliably do this you can use something like this.

const areTheNumbersAlmostEqual = (num1, num2) => {
    return Math.abs( num1 - num2 ) < Number.EPSILON;
}
console.log(areTheNumbersAlmostEqual(0.1 + 0.2, 0.3));
