Truthy and Falsy values

In JavaScript, a truthy value is a value that translates to true when evaluated in a Boolean context. All values are truthy unless they are defined as falsy.

Examples of Truthy values are: (which will be coerced to true in boolean contexts, and thus execute the if block):

if (true)
if ({})
if ([])
if (42)
if ("0")
if ("false")
if (new Date())
if (-92)
if (19n)
if (660)
if (-2.50)
if (Infinity)
if (-Infinity)

List of falsy values in JavaScript are:

1. false
2. null
3. undefined
4. 0
5. NaN
6. '', "", ``(Empty template string)

Example of Falsy value are:

if (false)
if (null)
if (undfined)
if (0)
if (Nan)
if ("")
if ('')
if (``)

There is another way of converting Truthy and Falsy values to Boolean are:

!!("0") // returns true
!! ("2") // returns true
