What Is A Boolean In Programming?

A boolean is a term used to represent either a state of true or false.

When it comes to programming, most languages for example, Python use the true and false construct for booleans:


01: b = True
02: type(b)
03: <class 'bool'>

For other languages or under certain conditions a 1 for True and a 0 for False can be used instead.

These states can then later be used in a conditional [→] to decide the direction a code execution flow should take.


01: 
02: var a = true
03: 
04: if(a) {
05:     console.log("a is true")
06: } else {
07:     console.log("a is not true")
08: }
