It's not that hard to understand what it is doing and why the decision was made to make it do that. JavaScript has a particular purpose and it's mission is not consistency.

It's not like TypeScript doesn't exist if you just get lightheaded at the idea of learning JavaScript's quirks and mastering using it despite them.

Oh we've hit an issue that's solved by another language or we could make another framework

If you're consciously and intentionally using JavaScript like that, I don't want to be friends with you.

It's because + is two different operators and overloads based on the type to the left, while - is only a numeric operator and coerces left and right operands to numeric. But frankly if you're still using + for math or string concatenation in 2025, you're doing it wrong.

I know nothing about javascript, what is wrong with using + for math? perhaps naively, I'd say it looks suited for the job

It's much better to make your own function that uses bitwise operations to do addition.

function add(a, b) {
    while (b !== 0) {
        // Calculate carry
        let carry = a & b;

        // Sum without carry
        a = a ^ b;

        // Shift carry to the left
        b = carry << 1;
    }
    return a;
}

(For certain definitions of better.)
