JS how to merge two arrays

JS how to merge two arrays:
This section describes how to merge two arrays, which I hope will help you a bit.
Instance code:
Example one:

var arrone=["Ant Tribe", "Shinan District, Qingdao", 3]; var arrtwo=["Share Exchange", "Antzone",];console.log (Arrone.concat (Arrtwo)); Console.log (Arrone); Console.log (arrtwo);

The output from the above code shows that the concat () function returns a new array instead of modifying the array, so the original two arrays are unchanged.
Example two:

var arrone=["Ant Tribe", "Shinan District, Qingdao", 3]; var arrtwo=["Share the Exchange", "Antzone", []; Array.prototype.push.apply (Arrone,arrtwo); Console.log (Arrone); Console.log (Arrtwo) ;

The above code can append elements from the arrtwo array to Arrone.
