JavaScript Converting a string to a boolean


Example

To convert a string to boolean use

Boolean(myString)

or the shorter but less clear form

!!myString 

All strings except the empty string (of length zero) are evaluated to true as booleans.

Boolean('') === false   // is true
Boolean("") === false   // is true
Boolean('0') === false  // is false
Boolean('any_nonempty_string') === true // is true
