    Say you have array named list. The Splice() function can be used for both adding and removing item in that array in specific index i.e that can be in the beginning or in the end or at any index. On the contrary there are another function name shift() and pop() which is capable of removing only the first and last item in the array.

    This is the Shift Function which is only capable of removing the first element of the array

    var item = [ 1,1,2,3,5,8,13,21,34 ]; // say you have this number series 
    item.shift(); // [ 1,2,3,5,8,13,21,34 ];
    

    The Pop Function removes item from an array at its last index

    item.pop(); // [ 1,2,3,5,8,13,21 ];
    

    Now comes the splice function by which you can remove item at any index

    item.slice(0,1); // [ 2,3,5,8,13,21 ] removes the first object
    item.slice(item.length-1,1); // [ 2,3,5,8,13 ] removes the last object 
    

    The slice function accepts two parameters (Index to start with, number of steps to go);
