Comments
Nashorn supports two types of comments:

• Single-line comments

• Multi-line comments

The syntax for writing comments in Nashorn is the same as that of Java. The
following are examples of comments:

// Let us declare a variable named empId (A single-line comment)
var empId;

/* Let us declare a variable named empList
and another variable named deptId (A multi-line comment)
*/
var empList;
var deptId;
