Heads up! 10 * '5' or '10' * '5' will give the same result. But trying to multiply a number with string values that aren’t numb

Question

From the question or statement made in the notes, what if we define or assign a string a value and then use that variable to compute an expression.

Var x = 5;
Var y = x + 6;
document.write(y);

My question is, would the code computer or give an error?

Answer 1

10 * '5'
Here '5' will be converted into Number. If succeeded, the conversion result (Number 5) will be multiplied by 10.

'10' * '5'
Here both will be converted to Number. If succeeded they both will be multiplied.

If either one was not convertible to Number you get NaN (Not a Number)
