ALT Image showing JavaScript code to reverse a number using math logic. The function checks if the number is negative, converts it to absolute value, then uses a while loop to extract digits using modulo and rebuild the reversed number. It returns the reversed number with original sign. Examples show 123 becomes 321 and -789 becomes -987.
ALT Image showing JavaScript code that calculates the factorial of a number using a for loop. The function checks for negative numbers and non-integer values, handles the base case, and returns the factorial result. Example shows calling the function with 5 and outputting 120.
ALT Image showing JavaScript code that prints even numbers from 1 to 50 using three methods. Method 1 uses the modulus operator to check even numbers, Method 2 uses an optimized loop incrementing by 2, and Method 3 stores even numbers in an array without using the push method.
ALT Image showing JavaScript code with three different methods to create an array containing numbers from 1 to 100. Method 1 uses the push() method, Method 2 assigns values using an index variable, and Method 3 uses the array length property to append values. The image compares different approaches that produce the same output.
