Array.of ()

The Array.of method is used to convert a set of values into an array. Array.of always returns an array of parameter values. If there are no arguments, an empty array is returned.

Array.of can basically be used instead of Array () or new Array (), and there is no overload due to different parameters. Its behavior is very uniform.

The main purpose of this method is to make up for the deficiency of the array constructor Array (). Because the number of parameters is different, the behavior of Array () will be different.

Array () / / [] Array (3) / / [,] Array (3,11,8) / / [3,11,8] Array.of () / / [] Array.of (3) / / [3] Array.of (3,11) Array.of (3). Length / / 1 Array.of (undefined) / / [undefined] Array.of (1) / / [1] Array.of (1,2) / / [1,2]

The Array.of method can be simulated with the following code:

Function ArrayOf () {return [] .slice.call (arguments);} this is all of the article "what's the use of the Array.of () method in ES6?" Thank you for reading!
