Implementation Code of JavaScript light copy and deep copy

What is "clone "?
In the actual programming process, we often encounter this situation: there is an object A, which contains some valid values at a time point, in this case, you may need a new object B that is exactly the same as a, and any subsequent changes to B will not affect the value in A. That is to say, A and B are two independent objects, however, the initial value of B is determined by object. In Java/javasript, a simple value assignment statement cannot meet this requirement. Although there are many ways to meet this requirement, the clone () method is the simplest and most efficient method. Of course, this method is not used in JavaScript.
Therefore, I specifically wrote two cloning methods: one for shortest replication and the other for deep replication.
Explanation:
Light copy (Shadow Clone): Only copies the basic type of the object. The object type still belongs to the original reference.
Deep replication (deep cloning): Copies the basic class of the object and the object in the original object, that is, completely generated by the new object. <Meta http-equiv = "Content-Type" content = "text/html; charset = gb2312 "> <meta name =" generator "content =" Wawa editor 1.0 "> <meta name =" author "content =" Eight gods "> <meta name =" keywords "content =" JavaScript, java, XML, XSLT, ASP, VBScript, Asp. net, C #, C ++, Database "> <meta name =" Description "content =" unqualified programmers, ubiquitous ">
