How do I merge two JavaScript objects?
An example of an AI chatbot conversation about merging JavaScript objects.
How do I merge two JavaScript objects?
You can use the Object.assign() method or the spread operator to merge objects in JavaScript.
Can you show me an example using the spread operator?
Sure! Here's an example:
const obj1 = { a: 1, b: 2 };
const obj2 = { b: 3, c: 4 };
const merged = {...obj1, ...obj2};
console.log(merged); // { a: 1, b: 3, c: 4 }
What happens if there are duplicate keys?
In case of duplicate keys, the values from the last object will overwrite the earlier ones.
Are there any other methods to merge objects?
Yes, you can also use libraries like Lodash which provide a merge function for deep merging.
