Just use arr slice startingIndex  endingIndex    If you do not specify the endingIndex  it returns all the items starting from the index provided   In your case arr arr slice 1

The easiest way is using shift    If you have an array  the shift function shifts everything to the left   var arr    1  2  3  4    var theRemovedElement   arr shift       theRemovedElement    1 console log arr       2  3  4
