Question:
Write a function isThreeDigit that checks if a number is greater than or equal to 100 and less than 1000.
Example: isThreeDigit(500) should return true and isThreeDigit(50) should return false.
Answer:
function isThreeDigit (n) {
return n >= 100 && n < 1000;
};
> create a function isThreeDigit
> has one parameter
> return statement is: n >= 100 && n < 1000
> two conditions passed for result to come true
> n has to be greater then or equal to 100 & less than 1000
