JavaScript Shallow Copy vs Deep Copy: Examples and Best Practices

TLDR Creating copies of objects and arrays in JavaScript can be challenging, as developers need to choose between shallow copies and deep copies. Shallow copies duplicate only top-level properties and share references for nested objects, whereas deep copies create entirely independent duplicates of all properties. Shallow copies are faster and suitable for flat structures, while deep copies are necessary for complex or nested objects. Understanding these differences is key to avoiding unintended side effects and performance issues in your code.
