How to use Javascript boolean type
Description
The Boolean type has two literal values: true
and false
.
These values are not numeric values.
These values are distinct from numeric values,
so true
is not equal to 1, and false
is not equal to 0.
true
and false
are case-sensitive,
so True and False are valid as identifiers but not as Boolean values.
Example
The following code creates two boolean type variables:
var isOK = true;
console.log(isOK);
var isNotOK = false;
console.log(isNotOK);
The code above generates the following result.
