JavaScript Code: // Recursive JavaScript function to check if a number is even.functionis_even_recursion(number){// If the number is negative, convert it to its absolute value.if(number<0){number=Math.abs(number);}// Base case: If the number is 0, it's even.if(number===0){return...
If the type guard passes, we use the expression num % 2 !== 0 to check if num is an odd number (i.e., its remainder when divided by 2 is not zero). If 'num' is not a valid number (fails the type guard) or is even, the function returns false. Finally, we test the "isOdd...
