JavaScript deepCopy和shallowCopy之间的区别 浅拷贝和深拷贝与语言无关。浅拷贝应尽可能少地重复。集合的浅表副本是集合结构的副本,而不是元素。对于浅表副本,现在两个集合共享各个元素。 示例 let innerObj = { a: 'b', c: 'd' } let obj = { x: "test", y: innerObj } //创建一个浅表副本。
deep = false; // Handle a deep copy situation 处理深拷贝 if ( typeof target === "boolean" ) { deep = target; // Skip the boolean and the target // 跳过布尔和目标,重新赋值target target = arguments[ i ] || {}; i++; }
deep = target; //Skip the boolean and the target //跳过布尔和目标,重新赋值target target = arguments[ i ] || {}; i++; } //Handlecasewhen target is a string or something (possibleindeep copy) //当目标是字符串或其他的时候(在深度拷贝中可能用到)处理用例 ...
Making a shallow copy of a window should correspond to opening a split view, where both instances share the same history. So, typing commands into the copy should be reflected in the original window and the other way around. Conversely, a deep copy should duplicate the original commands into...
