Let's work on improving our commenting skills by practicing with some code.

Task

Comment the second and the fifth lines of code.


              12345
            
console.log("line 1");
___ console.log("line 2");
console.log("line 3");
console.log("line 4");
___ console.log("line 5");

Use the single-line comment (//).


              12345
            
console.log("line 1");
// console.log("line 2");
console.log("line 3");
console.log("line 4");
