React is a JavaScript library for building user interfaces. It is maintained & developed by Facebook and a community of individual developers & companies. React can be used as a base in the development of single-page or mobile applications.
Let's see a few pro tips for React development
Tip - Use functional components rather than class component
This will accept 'props' as an argument and return React's element
Benefits of functional components are as below
- Easy to understand
- Less code
- No 'this' binding
- Easier to extract into smaller components
- Stateless
- Simpler to test
Tip - Use '&&' rather than 'if'
As per the above code, handling null value using if condition is a bit inconsistent, where '&&' will only be executed once the condition is satisfied totally. So use of '&&' is less coded with ease of understand.
Tip - Keep Component Small
Small components are easier to
- Read
- Test
- Re-use
- Maintain
Tip - Best way to use 'this'
Tip - Use a function in 'setState' rather than an object
According to React concept, It does not guarantee immediate state change possibility.
Function will receive previous state as its first argument, and props at the same time when update applied as its second argument.
Tip - Utilize prop-types
It is a library for typechecking props.
Tip - Separation of Styles
There are two approaches to use styling in react
- Using external .css or .scss files - easy to implement
- Use as a component, use their building styles - a little difficult
