# Comments in JavaScript Single line comments are handled with `//` while mult-line comments are handled with matching `/*` and `*/` pairs on separate lines: ``` /* This is a mult-line comment. **************************************************************** Everything in here is a comment. */ var FirstName = "John"; console.log(FirstName) //This is a single line comment, nothing in this line will be executed var LastName = "Smith"; var Age = 28; console.log(LastName) console.log(Age) var FullAge = true; console.log(FullAge); var job; console.log(job); job = "Teacher"; console.log(job) ```
