hello guys can someone give me an example in using Boolean in programme

Answer 1

Very often, in programming, you will need a data type that can only have one of two values, like

YES / NO
ON / OFF
TRUE / FALSE

JS

Boolean(10 > 9) // returns true

Or even easier:

(10 > 9) // also returns true
10 > 9 // also returns true

Boolean.prototype.myColor = function() {
if (this.valueOf() == true) {
return "green";
} else {
return = "red";
}
};

var a = true;
var b = a.myColor();

The value of b is now:
green

Answer 2

<!-- true or false is a boolean value -->
