 ## Q. What is Rest parameters?

+The rest parameter is used to pass zero or more values to a function. It is declared by prefixing the three **dot** characters **('...')** before the parameter. It allows the functions to have a variable number of arguments without using the arguments object.

 * Only one rest parameter is allowed in a function.
 * It must be an array type.
 * It must be a last parameter in the parameter list.
 
+**Example:**
+

+/**

     for (var i = 0; i < b.length; i++) {
