const a = '1';
isNumber(a); // returns true
const b = a + a; // Now you have a string in b: '11'
Of course, it's standard JS stupidity (and 2*a would be 2, and 1+'1' and '1'+1 would both be '11'), but then maybe stating that '1' is a number is not the right response. However, the package was downloaded 46 million times last week and that seems to be so low only because of Christmas. The previous weeks averaged around 70M. And most of these are dependencies, like in our projects, I'm sure.
