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.

What is CI/CD Pipeline?

TLDR Delivering quality software swiftly is essential in modern development. Continuous Integration and Continuous Delivery (CI/CD) pipelines help teams integrate code frequently and deploy it automatically, preventing integration issues and ensuring a reliable release cycle. Key stages in a CI/CD pipeline include source, build, test, and deploy. Popular CI/CD tools include GitHub Actions, Jenkins, TeamCity, CircleCI, and Azure DevOps. Optimizing your CI/CD pipeline involves identifying bottlenecks, streamlining builds, improving test efficiency, and leveraging caching. Choosing the right CI/CD platform depends on factors such as cloud-based versus self-hosted options, user-friendliness, and integration capabilities.

When Job Hopping Doesn't Make Sense

TLDR While job hopping is often seen as a fast track to higher pay and promotions early in a career, it may hinder growth at senior levels. At Staff+ positions, influence and credibility built within a company are key to advancement. Switching companies frequently resets these, slowing progress. Calculated career moves are essential later in your career to maintain momentum and minimize risk.
