Understanding The Basic Types Of React js Hooks

The developers were using hooks even before it was built in which the 16.8 version of react js. But the built-in hooks by react js helped the developers not only to reuse the code but also helped them to not disturb the code and make necessary changes.

Let’s see the brief and basic types of the react js hooks that have made react js coding simpler for the developers.

What Are React Js Hooks?

React is the most popular javascript technology that took over the technological world. The developers were using the hooks before react js brought the hooks as the inbuilt thing in react js.

Furthermore, it is important to take note that hooks are the functional component as earlier hooks were also able to get used with the class component.

Advantages Of React Js Hooks

React js being developer’s favorite there are many advantages that react js gives but react js hooks also have a significant contribution in the react js application development. Here are some of the advantages that will give you a brief about the advantages of react hooks.

• It advances the way of writing codes of the write component.
• Helps in writing clear and step-wise code.
• Hooks also help develop neat and tidy code and make code testing easier.
• You can customize the hook with the related logic or the formula that you want to add.
• Already react code is reusable hooks enhances its re-usability feature.
• The hooks don’t create an additional component or object in the DOM.
• Even though you can update it with new features, hooks remain the best option.
• Hooks can also be the best option for component folding whenever you require them in the future.

Rules Of Using Hooks

We all know that when you are coding something a single misplacing of the colon can also create an error. Hence is the same case for the hooks also. Knowing the rules of hooks can simplify your work and also help in reducing the developer’s work.

Here are a few rules of the react js hooks and how to use them:

1. Hooks should be called within the function

This is the primary rule and the most important one also. One should always call the hook within the logic components, nested functions, conditions, or loops.

2. Calling hooks only from react functions

One should always keep the hook entangled with the react not. As hook will not support the javascript component. You can also call hooks from the custom functions.

Why Hooks Was Introduced?

The introduction of hooks was brought with the new version of react which is React 16v8. The earlier versions of the hook were using stateless components and were only able to perform the state management and lifecycle methods.

Furthermore when the inbuilt hook came into the markets the problem of changing class components to functional components was resolved. This was the biggest aid for the react js developers.

Types Of Hooks

React js has a very confined type of hooks that have been ruling the IT industry for past years. With the popularity of Facebook, react also has come a far way along. Below are the types of react js hooks:

Built In Hooks

The built-in hooks are simplified into two categories basic react js hooks and additional hooks. Let’s take a look at these hooks and their use.

Basic Hooks

useState
This hook helps in tracking down the state present in the functional component. Moreover, the state here represents the property or the data that you need to be tracked down. Furthermore, it returns the variable value that you need to update by adding another component.

useContext
This hook helps in the passing of the data and state through the component tree. Moreover, it also doesn’t include the need to write down props manually through the nested components.

useEffect
The name itself suggests that this hook helps to nullify the effects caused by functional components. Moreover, this hook nullifies the effects like manipulation of the DOM and rendering of the timer.

Additional Hooks

useReducer
useReducer helps to pass the dispatch function in order to increase the productivity and ability of the component for the updation of the code.

useMemo
This hook avoids the expensive and important components to run uselessly. Moreover, it also gives you the result by calculating between the renders.

useCallback
Rendering is one of the basic things in react. This hook avoids the creation of each and every functional component to recreate again and again after each render.

useRef
This hook allows to storage of mutable values of any component. Moreover, it also helps in rendering the mutable component when updated.

useImperativeHandle
useImperativeHandle is the hook that has been helping the developers to define the value, function, or state inside the parent and child components.

useDebugValue
This hook is the informative hook that equips the developers with information on the internal logic of the custom hooks.

useLayoutEffect
This hook allows the customization of many things like spacing etc. Moreover, this hook allows the developers to change the page layout and inner calculations.

Conclusion

In conclusion to this, we can say that react js hooks play a very important role in the development of any application or website. Furthermore, with the enhancements of react hooks, there are many more such features that make react js impressively.

There are many businesses and companies that have to opt for react as their primary choice for software development. With the feature of responsive and interactive creation, react also helps in the easy deployment of the code.

If you want to develop a react js application then you should hire a react js developer that has expert knowledge about the pros and cons.
