Manipulating arrays in javascript.

Hi guys,
Today we are going to see ways in which arrays can be manipulated in javascript. We are going to focus on 4 main ways of doing that.

1. PUSH . The push function appends data at the end of an array. Take an example.

  var myArray = [] 
  myArray.push(1)
  console.log(myArray)

We can also use the push() function to append more than one element into an array.

  var myArray = [] 
  myArray.push(1,2,3)
  console.log(myArray)

2 . Pop function.
The pop function is used to remove the last element of an array and return the removed element.

    var myArray = [1,2,3,4]
    var removedArray = myArray.pop()
    console.log(removedArray)

3 . Shift function.
The shift function is used to remove the first element of an array and returns the removed element.

    var myArray = [1,2,3,4]
    var removedArray = myArray.shift()
    console.log(removedArray)

4 . Unshift function.
The unshift function is used to add elements at the beginning of an array.

    var myArray = [1,2,3,4]
    myArray.unshift(0)
    console.log(myArray)

That's all for today guys and I hope this short guide will help you understand the manipulation of arrays in javascript.
