Definitions

Evaluating to false in a Boolean context.

not-comparable

Examples

“In JavaScript, any expression or statement that expects a boolean value will work⟳ with a truthy or falsy value, so the fact that && does not always evaluate⟳ to true or false does not cause practical problems.”

“However, in the second case, both '0' and the empty string () are falsy (in other words, they behave like⟳ false) and are therefore equal with respect⟳ to ==.”

“If the first operand (which comes before the question⟳ mark⟳--doIt, in this example) is truthy, the expression evaluates to the second operand (between the question⟳ mark⟳ and colon), and if it's falsy, it evaluates to the third operand (after the colon).”
