![]() ![]() ![]() It is important to note that const declarations must be initialized at the time of declaration, otherwise they will throw an error. ![]() This will create a constant reference to the string “Hello World” which cannot be changed. To use const in ES6, simply declare the variable with the keyword const followed by the name of the variable. However, if the variable contains an object or array, then the contents of the object or array can still be modified. For example, if you declare a variable called “myVar” with const, then you cannot assign a new value to myVar. When using const, it is important to remember that the reference itself cannot be reassigned. Additionally, using const ensures that the code is more secure as it prevents malicious users from changing the values of variables. This can help to prevent accidental changes to the data and also makes it easier to debug any issues that may arise. This means that once you have declared a variable with const, its value cannot be changed. Using const for all of your references is a good idea because it helps to ensure that the data remains immutable. We’ll look at how to use arrow functions, classes, and other features to write better code and improve the performance of our applications. In this article, we’ll explore 10 best practices for using ES6. As developers, we should be aware of the best practices for using ES6 in order to take full advantage of its features and ensure our code is as efficient and maintainable as possible. ECMAScript 6 (ES6) is the latest version of the ECMAScript programming language, and it brings with it a host of new features and capabilities. ![]()
