WebDec 29, 2024 · 1. When you use == JavaScript will try very hard to convert the two things you are trying to compare to the same type. In this case 0 is converted to '0' to do the comparison, which then results in true. You can use ===, which will not do any type coercion and is best practice, to get the desired result.
