How to become front end developer

To become a front-end developer, you will need to learn some specific skills. Here are some steps you can follow to become a front-end developer: Learn HTML, CSS, and JavaScript: These are the basic building blocks of the web. HTML is used to structure content on the web, CSS is used to style it, and JavaScript is used to add interactivity. Get familiar with web design principles: This includes things like layout, color theory, typography, and user experience (UX). Learn a front-end framework: There are many frameworks to choose from, such as React, Vue, or Angular. These frameworks can make it easier to build web applications, as they provide a structure for your code and a set of tools for common tasks. Practice by building projects: The best way to learn is to get hands-on experience. Try building your own websites or web applications, and use online resources to learn new techniques.

What is redux toolkit in react

React Redux Toolkit (RTK) is a popular library for building applications with the React library and the Redux state management library. It provides a set of tools and utilities that simplify the process of working with React and Redux, making it easier to build scalable and maintainable applications. One of the key features of RTK is its createSlice function, which makes it easier to create and manage redux reducers and actions. With createSlice, you can define your reducer logic and action creators in a single place, and RTK will handle the creation of the corresponding reducer and action types for you. This helps to reduce boilerplate code and make your redux logic easier to understand. Another useful feature of RTK is its configureStore function, which helps you to configure and create a Redux store for your application. It provides a set of options that allow you to customize the store to your needs, such as enabling the Redux DevTools extension or adding middleware for async act

What's the difference between using “let” and “var” ?

"Let " is the statement introduced by ES6(ECMA Script 6). What is this "Let" and how it behaves . Let us discuss about this in this post . What is "let" We are very familiar with key word "var" , which will help us to create a variable in Java script . In ES6 this "let " word used to declare a variable . but both "let " and "var" behaves differently . The main difference is scoping. var will be scoped to the nearest function block and let will be scoped to the nearest enclosing block (both "let " and "var" are global if outside any block), which can be smaller than a function block. And one more thing to be noted is , variables declared with let are not accessible before they are declared in their enclosing block. As seen in the demo, this will throw a ReferenceError exception.
