The program illustrates the use of a loop statement.
Loop statements are used to perform repetitive operations; examples are for-loop and while-loop.
The 5.7.5 codehs program in Javascript where comments are used to explain each line is as follows:
//This defines the factorial function
function factorial(n){
if (n < 3){
//This returns n, if n is less than 3
return n;
}
//If n is not less than 3
else{
//This initializes the factorial to 1
let fact = 1;
This iterates through n, starting from 2
for(var i = 2; i <= n; i++){
//This calculates the factorial
fact = fact * i
}
//This returns the factorial
return fact;
}
}
At the end of the program, the factorial of the number is calculated and returned.
