Join Eve Porcello for an in-depth discussion in this video Updating and removing notes, part of Learning React.js (2016).
- [Instructor] In this video we're going to create functions…that are going to handle updating and removing notes.…The first thing I want to do here…is I want to change our notes array…and I want to change these notes to be objects.…So the object is going to have a key of id…and then it's going to have a key of note…and that's just going to be set equal…to whatever the string is.…So let's go ahead and create these for all four of our notes…and we're going to go ahead and update the ids…zero, one, two, three.…
We'll say Email Sarah, Eat Lunch,…and Finish proposal.…Awesome.…So this is going to help us process these notes…a little bit easier when we start to update and remove them.…Speaking of that, let's go ahead and add our update method.…Update is going to handle the editing of notes…so the update method is going to take…in new text and the id.…And then we're going to create a variable called notes.…
This is going to be set to our notes in state…and we're going to map over those…and depending on whether or not this note should be updated…
