Higher-Order Components In React

2. Byteridge Introduction • Hello readers, today we are going to learn about higher-order components, the syntax of higher-order components, as well as a few use cases for them. In the process, we will build a higher-order component from an existing React component. By the end of this tutorial, you will understand the basics of higher-order components and how to build them. • Higher-order components (HOCs) in React were inspired by higher-order functions in JavaScript. A HOC is an advanced technique for reusing logic in React components. It is a pattern created out of React’s compositional nature. .

3. Byteridge Higher-Order Functions • forEach(): This iterates over every element in an array with the same code, but does not change or mutate the array, and it returns undefined. • filter(): This checks every single element in an array to see whether it meets certain criteria as specified in the filter method, and then it returns a new array with the elements that match the criteria.

4. Byteridge Higher-Order Functions • map() : This method transforms an array by applying a function to all of its elements, and then building a new array from the returned values. • reduce() : This method executes a provided function for each value of the array (left to right).

Byteridge CUSTOM HIGHER-ORDER FUNCTION const formatCurrency = function( currencySymbol, decimalSeparator ) { return function( value ) { const wholePart = Math.trunc( value / 100 ); let fractionalPart = value % 100; if ( fractionalPart < 10 ) { fractionalPart = '0' + fractionalPart; } return `${currencySymbol}${wholePart}${decimalSeparator}${fractionalPart}`; } }
