Logical Operators: Not (!)

The logical not operator (!) is used to invert the value of a boolean condition. For example:

7 <= 10 // Evaluates to true
!(7 <= 10) // Evaluates to false

12 != 12 // Evaluates to false
!(12 != 12) // Evaluates to true

!true // Evaluates to false

It is often used with boolean variables:

let hungry = true;
if(!hungry) {
    console.log("I can wait a little longer");
}
else {
    console.log("I need food!");
}

!hungry evaluates to false, so we enter the else and print "I need food!".
