C# provides two methods to link value type to reference type and vice e Versa. These two methods for linking are named boxing and unboxing where Boxing is used for the conversion of the value type to an object type while Unboxing refers to the conversion of the object type to the value type.The following are the important differences between Boxing and Unboxing.Sr. No.KeyBoxingUnboxing1ImplementationBoxing made object type referred to as the value type.Unboxing basically processes the retrieving value from the boxed object.2StorageIn the case of boxing, the value stored on the stack is copied to the object stored on heap ...

The Object.assign() method is used to copy the values of all of the object's own properties(enumerable only) from one or more source objects to a target object. It will return the target object.Exampleconst targetObj = { a: 1, b: 2 }; const sourceObj = { b: 4, c: 5 }; const returnedTarget = Object.assign(targetObj, sourceObj); console.log(targetObj); console.log(returnedTarget); console.log(returnedTarget === targetObj); console.log(sourceObj);Output{ a: 1, b: 4, c: 5 } { a: 1, b: 4, c: 5 } true { b: 4, c: 5 }Note −sourceObj did not change.returnedTarget and targetObj are the same.The Object.assign() method only copies enumerable and own properties from ...
