So far, you’ve seen props passed a static value, like in: All props form a one-way-down binding between the child property and the parent one: when the parent property updates, it will flow down to the child, but not the other way around.
This prevents child components from accidentally mutating the parent’s state, which can make your app’s data flow harder to understand.
In these cases, you can list props as an object, where the properties’ names and values contain the prop names and types, respectively: This not only documents your component, but will also warn users in the browser’s Java Script console if they pass the wrong type.
Migrations are like version control for your database, allowing your team to easily modify and share the application's database schema.To use our schema definition, we need to convert our calls succeeded or when there was an error.While nice for development, it is recommended this behavior be disabled in production since index creation can cause a significant performance impact.HTML attribute names are case-insensitive, so browsers will interpret any uppercase characters as lowercase.That means when you’re using in-DOM templates, camel Cased prop names need to use their kebab-cased (hyphen-delimited) equivalents: Usually though, you’ll want every prop to be a specific type of value.
