concat

function

Merge many collections together into a List.

`list.concat(...args)`

Parameters

args {Array|can.List|*}:
Any number of arrays, Lists, or values to add in For each parameter given, if it is an Array or a List, each of its elements will be added to the end of the concatenated List. Otherwise, the parameter itself will be added.

var list = new can.List();
var newList = list.concat(
    'Alice',
    ['Bob', 'Charlie']),

    {f: 'Francis'}
);
newList.attr(); // ['Alice', 'Bob', 'Charlie', 'Daniel', 'Eve', {f: 'Francis'}]
