Replace an object in array with another object in javascript

Posted on September 8, 2024

To replace an object in an array with another object in JavaScript, you typically need to know the index of the object you want to replace. Here's how you can do it:

Method 1: Using indexOf

First, find the index of the object you want to replace:

const index = list.indexOf(myObject);

Then, replace the object at that index:

list[index] = newObject;

This method works well when you know the reference to the object you're replacing.

Method 2: Using splice

Another way to replace the object is to use the splice method:

list.splice(index, 1, newObject);

This will remove the object at the specified index and insert the newObject in its place.

Conclusion

There are other ways to do this, but I recommend sticking with either the indexOf or splice methods for simplicity and clarity.
