前面的语句都是判断,知道最后的copy_array(s, src_pos, d, dst_pos, length, thread)是真正的copy,进一步看这里,在openjdk6-src/hotspot/src/share/vm/oops/typeArrayKlass.cpp中: voidtypeArrayKlass::copy_array(arrayOop s,intsrc_pos, arrayOop d,intdst_pos,intlength, TRAPS) { assert(s->is_ty...
Use slice() to Copy Array Elements From an Array in JavaScript Use Spread ... Operator to Copy Array Elements From an Array in JavaScript In this article, we will learn how to copy elements of an array into a new array of JavaScript. In JavaScript, arrays are normal objects containing...
One of the ways of creating a deep copy of an object in JavaScript is using the structuredClone() method. The method uses a structured clone algorithm that deep clones an object.The method takes the object which is to be cloned as the parameter. Let’s perform the cloning....
