Integration with Modern Frameworks

React

Lodash can be very useful in React applications for managing state, handling events, and transforming data.

• Optimizing Render Performance: Use _.memoize to avoid unnecessary re-computations.

import React, { useMemo } from 'react'; import _ from 'lodash'; const computeExpensiveValue = (input) => { // Simulate an expensive computation return input * 2; }; const MemoizedValue = _.memoize(computeExpensiveValue); const MyComponent = ({ input }) => { const result = useMemo(() => MemoizedValue(input), [input]); return <div>{result}</div>; };

• Handling Collections: Use Lodash to process arrays of data before rendering.

import React from 'react'; import _ from 'lodash'; const data = [ { id: 1, name: 'John' }, { id: 2, name: 'Jane' }, { id: 3, name: 'Doe' } ]; const MyComponent = () => { const sortedData = _.sortBy(data, 'name'); return ( <ul> {sortedData.map(item => ( <li key={item.id}>{item.name}</li> ))} </ul> ); };

Vue

Lodash can be integrated into Vue components for similar tasks, such as optimizing event handlers and processing data.

• Debouncing User Input:

import Vue from 'vue'; import _ from 'lodash'; new Vue({ el: '#app', data() { return { query: '' }; }, methods: { search: _.debounce(function() { console.log(`Searching for: ${this.query}`); }, 300), onInput(event) { this.query = event.target.value; this.search(); } } });

• Data Filtering and Sorting:

import Vue from 'vue'; import _ from 'lodash'; new Vue({ el: '#app', data() { return { items: [ { id: 1, name: 'Banana' }, { id: 2, name: 'Apple' }, { id: 3, name: 'Cherry' } ], filter: '' }; }, computed: { filteredItems() { return _.filter(this.items, item => item.name.toLowerCase().includes(this.filter.toLowerCase())); }, sortedItems() { return _.sortBy(this.filteredItems, 'name'); } } });
