JavaScript Essentials for React Native - SERIES
JavaScript concepts required for React Native
A lot of beginners struggle with React Native as their JavaScript concepts are weak. This series will cover the most common JavaScript concepts used in React Native aiming to make your React Native App Development journey easier.
Why JavaScript foundations are crucial for React Native Development ?
JavaScript serves as the core programming language for React Native development, and a strong foundation in JS is crucial for many reasons:
React Native is Built on JavaScript
React Native uses React.js which is a JavaScript library
You write your frontend code i.e UI in JavaScript in React Native
All your Business logic is also in JavaScript
Handling asynchronous tasks such as fetching data from API / handling user interactions etc require understanding of JavaScript's asynchronous features
Fetching data, saving data, showing data on UI, reformatting data as per different use cases also requires knowledge of JS data structures - arrays, objects and standard functions like map, filter, reduce
Debugging and Testing also uses JavaScript libraries and tools
I am going to write 6 articles in this series to cover different topics.
And as and when those articles are published their links will be added here itself so that you can easily navigate.
