undefined ? "print":"not print" what is output...?

undefined ? "print" : "not print"

is a ternary operator in JavaScript. The ternary operator works as follows:

condition ? expressionIfTrue : expressionIfFalse

• If the condition evaluates to true, it returns expressionIfTrue.

• If the condition evaluates to false, it returns expressionIfFalse

Explanation:

The condition is undefined:

In JavaScript, undefined is a falsy value. This means it is treated as false in boolean contexts.

What happens in the ternary operator?:

The condition undefined evaluates to false.

Since the condition is false, the operator will return the second expression, which is "not print"

Output:

"not print"

This is because undefined is falsy, and the ternary operator selects the expression after the colon (:) when the condition is false.
