When should I use const in JavaScript?
An example of an AI chatbot conversation about using 'const' in JavaScript.
When should I use 'const' in JavaScript?
You should use 'const' when you want to declare a variable that won't be reassigned. It's great for constants.
Can you give me an example of using 'const'?
Sure! For instance, you can declare a constant like this: const pi = 3.14; This value won't change.
What happens if I try to reassign a 'const' variable?
If you try to reassign a 'const' variable, you'll get a TypeError. It helps prevent accidental changes.
Are there any exceptions to using 'const'?
Yes, you can still modify properties of objects declared with 'const', but you can't reassign the variable itself.
