Truthy and Falsey values

Any value in Javascript can be considered a boolean if necessary.

Example:

if (2) {
  console.log("Is 2 Truthy?")
}

The most obvious place is in if conditions.

Everything in Javascript is truthy except:

• false
• 0 (the number 0)
• "" (empty string)
• null
• undefined
• NaN (not a number)
• -0
• 0n
