Programming Command: Syntax Highlighting

Below is an example of programming command syntax highlighting:

        
            function calculateSum(num1, num2) {
                let sum = 0;
                for (let i = 0; i < arguments.length; i  ) {
                    sum  = arguments[i];
                }
                return sum;
            }
            // Usage example:
            let result = calculateSum(10, 20, 30);
            console.log('The sum is '   result);
