What are some common mistakes when using const in JavaScript?
An example of an AI chatbot conversation about common mistakes with const in JavaScript.
What are some common mistakes when using const in JavaScript?
One common mistake is trying to reassign a value to a variable declared with const. This will throw an error.
Can you give me an example of that?
Sure! If you declare const x = 10; and then try to do x = 20;, it will result in a TypeError.
Are there any other mistakes people make?
Yes, another mistake is misunderstanding that const only prevents reassignment, not mutation. For example, you can still modify properties of an object declared with const.
So, I can change the contents of an array declared with const?
Exactly! You can modify the array's elements, but you can't reassign the array itself.
