Understanding ES6 and beyond
const are block-scoped variables that allow you to declare variables within a block of code, such as a loop or an if statement. This helps prevent accidental variable reassignment and reduces the risk of bugs in your code.
Modules and module bundlers
Webpack is a module bundler that allows you to bundle multiple modules into a single file for deployment. It also provides a range of other features, such as code splitting and hot module replacement, that can significantly improve the performance of your website.
ESLint is a tool that helps you write cleaner and more maintainable code by identifying potential errors and enforcing coding standards. It can be customized to suit your specific coding style and project requirements.
Firstly, you should always use strict mode to enforce stricter rules on your code. This can help prevent common errors and make your code more reliable.
Secondly, you should use let and const instead of var to declare variables. This helps prevent accidental variable reassignment and makes your code more readable.
Thirdly, you should use arrow functions instead of regular functions wherever possible. This can significantly reduce the amount of boilerplate code in your project and make it easier to read and maintain.
