Question

In JavaScript, Define a function which takes a number as a parameter and if the number is less than 0 or higher than 100, display the message, “the number is NOT a valid number”, otherwise display “the number is a valid number”.

Answer 1

Code:

//Function definition for checking the validity of the number
function parameterValid(number) {
   // If the number is less than 0 or higher than 100
   if(number < 0 || number > 100){
       // Print that it is not a valid number
       console.log("The number is NOT a valid number");
   }
   // Else
   else {
       // Print that it is a valid number
       console.log("The number is a valid number");
   }
}

// Calling the function with different parameters
parameterValid(-120)
parameterValid(42)
parameterValid(234)
