Get the last element of the array

Array.prototype.slice (begin,end) can be used to crop arrays. However, if the value of the ending parameter end is not set, the function automatically sets end to the array length value. I think few people know that this function can accept negative values. If you set begin to a negative number, you can get the reciprocal elements from the array:

Var array = [1,2,3,4 array.slice (- 1)]; console.log (array.slice (- 1)); / / [6] console.log (array.slice (- 2)); / / [5je 6] console.log (array.slice (- 3)); / / [4Jing 5J 6] above is all the content of the article "how to get the last element of an array".
