설명

Concat joins two or more arrays.

The method does not change the existing arrays and returns a copy of the joined array.

function Start () {
    var arr = new Array ("Hello", "World");
    var arr2 = new Array ("!");

// joined now contains all 3 strings var joined = arr.Concat(arr2);

// prints "Hello","World","!" print(joined); }

Note: This is javascript only. C# does not use this feature.
