After working in the React ecosystem for a long time, I decided to venture into mobile app development. React Native was particularly appealing because it offered the ability to develop native mobile applications using my existing JavaScript and React knowledge.
JavaScript provides two primary ways to define functions: Traditional Functions and Arrow Functions. While both serve the same fundamental purpose of executing tasks, they differ significantly in terms of syntax, behavior, and specific use cases.
Axios is not a part of React; it can be used with any frontend framework. Axios is not your only option, but it is certainly one of the most popular. You can customize it according to your project's needs by using each of Axios's fundamental HTTP methods. Axios is a popular JavaScript library used for making HTTP requests...

The concept of scope is quite easy and very important topic in javascript. So let's delve deeper into this issue. Scope is the ability of our other code pieces to access this value or not, depending on where the variable defined is located. In other words, we can access variables, objects, functions according to their scope...
