We can pass spread props along with regular props in React:
We can even spread multiple objects while passing props to a component:
However, it is necessary to understand that if multiple values are provided for the same prop, the component will get the value specified last.
To illustrate this concept, let's consider an example with a Settings
component that accepts the following props:
theme
(either "dark" or "light")
language
isNotificationEnabled
We have two objects: defaultSettings
and userSettings
.
We can use these objects to pass props to the Settings
component. Now, let's examine different scenarios to understand how the ordering of props affects the values:
-
When we pass only defaultSettings
using spread syntax:
-
When we pass defaultSettings
using spread syntax, but also explicitly set theme
to "dark":
-
When we pass defaultSettings
using spread syntax, and then pass userSettings
using spread syntax:
-
When we explicitly set theme
to "light", language
to "spanish", and then pass userSettings
using spread syntax:
By changing the ordering of props, we can control the values of props received by the component and ensure the desired behavior.
