An example of an AI chatbot conversation about the 'const' keyword in JavaScript.
What is the purpose of 'const' in JavaScript?
The 'const' keyword is used to declare variables that cannot be reassigned. It ensures that the variable's reference remains constant.
Can I still change the properties of an object declared with 'const'?
Yes, you can change the properties of an object declared with 'const'. The 'const' keyword only prevents reassignment of the variable itself.
What happens if I try to reassign a 'const' variable?
If you try to reassign a 'const' variable, JavaScript will throw a TypeError, indicating that you cannot reassign a constant variable.
Are there any best practices for using 'const'?
It's best to use 'const' for variables that should not be reassigned, which helps in maintaining code clarity and preventing bugs.
