The value converted to false in Js

Values ​​in JavaScript can be divided into the following two categories:

1. A value that can be coerced to false
2. Other (values ​​cast to true) The
   JavaScript specification specifically defines a small set of values ​​that can be cast to false.
   The abstract operation ToBoolean is defined in section 9.2 of the ES5 specification, enumerating all possible
   outcomes .
   These are falsy values:
   • undefined
   • null
   • false
   • +0 , -0 and NaN
   • Boolean coercion of ""
   falsy value results in false .
