Flyweight pattern would be an acceptable use of a shallow copy. Lazy copying is also a shallow copy. Shallow copies are quicker to make, which is often desirable for obvious reasons. The ultimate in shallow copying is obviously just a copy of a reference to the original object. If you're ...
The figure below illustrates the Deep Copy, 2) Shallow Copy The shallow copy method of copying contents is a technique in which the changes made in the copied object are reflected in the original object. This shows that the new object copy created and the original object share the same memor...
shallow copy vs deep clone Ashallow copyof an object is a copy whose properties share the samereferences(point to the same underlying values) as those of the source object from which the copy was made. As a result, when you change either the source or the copy, you may also cause the ...
Shallow copy One method of copying an object is the shallow copy. In the process of shallow copying A, B will copy all of A's field values. he field value is a memory address it copies the memory address, and if the field value is a primitive type it copies the value of the primit...
Shallow copy[edit] One method of copying an object is the shallow copy. In the process of shallow copying A, B will copy all of A's field values.[1][2][3][4]If the field value is a memory address it copies the memory address, and if the field value is a primitive type it cop...
Shallow copying of an object will not clone the child objects. Hence, the child copy is not fully independent of the parent. A deep copy of an object will recursively clone the child object and hence the child object is fully independent of the parent. Creating a deep copy is slower. ...
Deep copy can be many times slower than the shallow copy. Shallow copy involves copying only from one level of an object, while deep cloning involves recursively copying all mutable types (involve multiple levels) that can have a significant impact on performance. Shallow copy is preferred if an...

Generally, I thinkObject.assign({}, someThing)is often a red flag because if not today, maybe in some future the thing you're copying might have mutables within. The "solution" is to usestructuredClonewhich has been available since Node 16. Actually, it was introduced within minor releases...
