Why typeof 1===1 returns false instead of boolean [duplicate]

Question

From MDN website if you look at typeof operand
Def: operand is an expression representing the object or primitive
we know that 1===1 // returns true it is a primitive type boolean and
typeof true // always returns boolean

But when i run below code

console.log(typeof 1===1);

I don't understand why it returns false instead of boolean

Answer 1

Since the typeof operator comes with a higher precedence then ===:

• The first operation is actually typeof 1 which returns a "number".
• The next operation is "number" === 1, which return false, because obviously a string isn't a number.

If you want to make it work, use parentheses inside to process the comparison (1 === 1) first and then check its type.

console.log(typeof (1 === 1));
