An example of an AI chatbot conversation about handling mutable data in JavaScript.
How do I handle mutable data in JavaScript?
In JavaScript, mutable data refers to objects and arrays that can be changed after their creation. You can handle them using methods like push, pop, or by directly modifying properties.
Can you give me an example of modifying an object?
Sure! Here's an example: let obj = { name: 'Alice' }; obj.name = 'Bob'; // Now obj is { name: 'Bob' }.
What about arrays? How do I modify them?
For arrays, you can use methods like .push() to add elements or .splice() to remove them. For example: let arr = [1, 2, 3]; arr.push(4); // Now arr is [1, 2, 3, 4].
