JavaScript Object Copying Guide: Shallow vs Deep Copying Techniques Explained

JavaScript developers need to master object copying for data manipulation. Shallow copies share references, affecting original data. Creating them involves Object.assign() or the spread operator. Deep copies create independent data by recursively copying properties, and methods like JSON.parse() and lodash cloneDeep() are used. Best practices include understanding differences and considering performance implications.
