1. false – Boolean false
2. 0 – The number zero
3. 0 – Negative zero
4. 0n – B igInt zero

7. undefined – A variable that has not been assigned a value
8. NaN – "Not a Number", a value representing invalid number results

Truth Values

In JavaScript, truthy values are all values that are not falsy. These values are considered true when evaluated in a Boolean context. Here is a list of truthy values:

1. true – Boolean true
2. Non-empty strings – Any string that is not empty (e.g., "hello", " ").
3. Any non-zero number – Positive or negative numbers other than 0 and 0 (e.g., 1, 5, 3.14).
4. Any non-zero BigInt – BigInt values other than 0n (e.g., 1n, 1000n).
5. Objects – All objects, even empty ones (e.g., {}, [], function() {}).
6. Arrays – Even empty arrays (e.g., [], [1, 2, 3]).
7. new Date() – A Date object (e.g., new Date()).
