What does 'const' mean in JavaScript?
An example of an AI chatbot conversation about using 'const' for immutable variables in JavaScript.
What does 'const' mean in JavaScript?
In JavaScript, 'const' is used to declare variables that cannot be reassigned. It creates an immutable reference.
Can you give me an example of using 'const'?
Sure! Here's an example: const pi = 3.14; You cannot reassign pi to another value.
What happens if I try to change a 'const' variable?
If you try to reassign a 'const' variable, you'll get a TypeError. For example, pi = 3.14159; will fail.
Are there any exceptions to this rule?
Yes, while the reference is immutable, if the 'const' variable is an object or array, you can still modify its properties or elements.
