JavaScript adding a string to a number

Question

I was reading the re-introduction to JavaScript on MDN and in the section Numbers it said that you can convert a string to a number simply by adding a plus operator

Answer 1

A smple + operator in javascript is used for concatenation and not to add.

A bracket and a + operator before the string format integer variable will do the job every time.

This always works fine.

1 + (+"2") = 3

Because placing + before string converts the string variable into number.
