concat(nodes, [node2, ...]) ⇒ self Modify the collection by adding elements to it. If any of the arguments is an array, its elements are merged into the current collection. This is a Zepto-provided method that is not part of the jQuery API. contents v1.0+ contents() ⇒ coll...
concat(nodes, [node2, ...]) ⇒ self 添加元素到一个Zepto对象集合形成一个新数组。如果参数是一个数组,那么这个数组中的元素将会合并到Zepto对象集合中。 这是一个Zepto提供的方法,不是jquey的API 。 contents v1.0+ contents() ⇒ collection 获得每个匹配元素集合元素的子元素,包括文字和注释节点。

The difference for the immutable collections is that methods which would mutate the collection, likepush,set,unshiftorsplice, instead return a new immutable collection. Methods which return new arrays, likesliceorconcat, instead return new immutable collections. ...
It must return an array containing two arrays. The first is an array of strings, the second is an array of values. The pre plugin can be used to reshape the strings array and/or apply mutations to the interpolated values. An example of a Pre plugin could be to apply a transform, turn...
