const keyword is used to declare a constant, which is a variable that cannot be reassigned after it has been declared.
Here’s an example of how to use the
const MAX_ATTEMPTS = 10; console.log(MAX_ATTEMPTS);
In this example, a constant named
MAX_ATTEMPTS is declared with the value
10. The naming convention for constants is to use all uppercase letters and separate words with an underscore. This makes it easy to identify which variables are meant to be constant and helps to prevent accidental reassignment.
It’s also a good practice to declare constants at the top of your code, or within a specific module, to make it clear what the scope of the constant is. Additionally, make sure to give the constant a descriptive name that accurately represents its purpose and value.
In general, it’s a good idea to use constants whenever you need to use a value that should not change throughout the life of your program. This can help to make your code more readable, maintainable, and less prone to bugs.
