It seems it is that way, which is weird. You should always convert to the widest type, meaning string for comparing numbers and strings. I just checked that 1 == "01" is true, which means that “01” gets cast to an integer. And according to the document it might be that for example 1 == "a" would basically be interpreted as 1 === NaN which is false.

Doesn’t it widen the types regardless of position? Meaning 1 == “1” will be compared as strings, not numbers.

mdn goes into it more and it’s way more involved than I thought, looks like order of operand doesn’t matter. see the number to string section
