Higher-order components (HOCs) are an advanced topic in React.js, often used by <\/span>application development experts<\/span> to streamline the code and make the development project more efficient. A <\/span>HOC<\/span><\/a> is a \u201cfunction that takes a component and returns a new component\u201d. It reuses component logic and follows one of the patterns.<\/span><\/p>\n

When do you use HOCs?<\/span><\/h3>\n

Let\u2019s say you have a box to which you want to add an outline color. A component would perform this activity. Now let\u2019s say you have ten similar boxes, each needing an outline color. You could hand-write code for each box, or use a HOC to create a function that provides an outline color for each.<\/span><\/p>\n

Here\u2019s an example of a function that creates a new component: a HOC<\/span><\/h3>\n

import React from \u2018react\u2019<\/span><\/p>\n

const higherOrderComponent = WrappedComponent => {<\/span><\/i><\/p>\n

\u00a0\u00a0class HOC extends React.Component {<\/span><\/i><\/p>\n

\u00a0\u00a0\u00a0\u00a0render() {<\/span><\/i><\/p>\n

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0return <WrappedComponent \/><\/span><\/i><\/p>\n

\u00a0\u00a0\u00a0\u00a0}<\/span><\/i><\/p>\n

\u00a0\u00a0}<\/span><\/i><\/p>\n

\u00a0\u00a0return HOC<\/span><\/i><\/p>\n

}<\/span><\/i><\/p>\n

In the above example, a higher-order component is written as a function. It takes a component, called \u2018WrappedComponent\u2019, as an argument. We have created a new component called \u2018HOC\u2019, which returns the <WrappedComponent\/> from its render function.<\/span><\/p>\n

 <\/p>\n

A higher-order component (HOC) is a distinctive element for reusing logic in React components.<\/span><\/p>\n

How do you use Higher-Order Components?<\/span><\/h3>\n
    \n
  1. HOCs don\u2019t modify or mutate components; they create new ones<\/span><\/li>\n
  2. The code can be reused as required<\/span><\/li>\n
  3. No side effects arise from the use of HOCs in <\/span>React.js development services<\/span><\/li>\n<\/ol>\n

    What are the benefits of using HOCs?<\/span><\/h3>\n
      \n
    1. When used properly and efficiently, HOCs are easy to handle<\/span><\/li>\n
    2. HOCs help to streamline the code by avoiding mutating or comoving the same logic in each component created<\/span><\/li>\n
    3. Using higher-order components makes code more readable and efficient<\/span><\/li>\n
    4. Due to its proper naming conventions, debugging becomes easy<\/span><\/li>\n<\/ol>\n

       <\/p>\n
