Certain JavaScript operators perform implicit type conversions and are sometimes used explicitly for the purpose of type conversion. If one operand of the + operator is a string, it converts the other one to a string. The unary + operator converts its operand to a number. And the unary ! operator converts its operand to a boolean and negates it. These facts lead to the following type conversion idioms that you may see in some code: x + "" // => String(x) +x // => Number(x) x-0 // => Number(x) !!x // => Boolean(x): Note double !
