Join Eve Porcello for an in-depth discussion in this video Setting properties, part of Learning React.js (2016).
- [Woman] In this video we want to use the component…life cycle to set properties.…First let's remove some content from our index.html file…and the first thing I wanna remove here…is everything about getting rid of the box,…I'll remove component did mount and will mount,…and then I'm going to add a new method here called…getDefaultProps.…Get default props will be called once before the component…renders to set up defaults for our component.…
So in this method we're actually going to handle…all of our styling via getDefaultProps…rather than this style tag.…So we want to return an object that passes all of this…information about our desired style.…So let's go ahead and cut and paste this…directly into our return statement.…Let's also remove our style tag…since we aren't going to need that anymore,…and we're going to make a few little adjustments…here to the object being returned.…
