A center equipped to handle a large volume of telephone calls. These calls could be the calls coming in from customers for service or support or these could be the calls that call center executives make to the customers for marketing

There are mainly two types of call centers :

a) Inbound call centers – Inbound call centers are those which receive support or service calls from customers usually on a toll free number. For e.g. when you call up a bank to check the status of your request for credit card, it is an inbound call.

-The shift() method is similar as the pop() method but the difference is that Shift method works at the beginning of the array. 

-The shift() method take the first element off of the given array and returns it. The array on which is called is then altered.

For example

var myarray = ["apple ", "banana ", "mango "]; 

console.log(myarray.shift());

console.log(myarray);

we get the following console output:

apple

["banana ", "mango "];

When we call shift() on an empty array, it will return an undefined value.
