JavaScript 是一种极其通用且功能强大的编程语言,广泛用于 Web 开发。无论您是经验丰富的开发人员还是新手,拥有一组方便的 JavaScript 代码片段都可以节省您的时间并简化您的编码过程。在本文中,我编译了 15 个简短而精彩的 JavaScript 片段,涵盖了各种任务。让我们潜入吧!
const currentDateTime = new Date(); console.log(currentDateTime);
const number = [5, 2, 7, 10, 1] const maxNumber = Math.max(...number) // 10
function shuffleArray(array) { return array.sort(() => Math.random() - 0.5); }
const randomNumber = Math.floor(Math.random() * 10) + 1; console.log(randomNumber); // 7
const str = 'Hello, World!'' console.log(str.toLowerCase()); // hello, world!
const num = 5; if (num % 2 === 0) { console.log('Number is even'); } else { console.log('Number is odd'); } // 'Number is odd'
let seconds = 5; const countdown = setInterval(() => { console.log(seconds); seconds--; if (seconds < 0) { clearInterval(countdown); console.log('Countdown finished!'); } }, 1000); // 5 // 4 // 3 // 2 // 1 // Countdown finsihed!
const numbers = [1, 2, 3, 4, 5]; const strings = numbers.map(String); console.log(strings); // ['1', '2', '3', '4', '5']
let arr = ["apple", "mango", "apple", "orange", "mango", "mango"]; const removeDuplicates = arr => [...new Set(arr)]; console.log(removeDuplicates(arr)); // ['apple', 'mango', 'orange']
const sentence = "This is a sentence"; const words = sentence.split(" "); console.log(words); // ['This', 'is', 'a', 'sentence']
function repeatString(str, n){ return str.repeat(n); } const repeatedStr = ('abc', 3); console.log(repeatedStr); // 'abcabcabc'
// Define the intersection function const intersection = (a, b) => a.filter(value => b.includes(value)); // Example arrays const arrayA = [1, 2, 3, 4, 5]; const arrayB = [4, 5, 6, 7, 8]; // Use the intersection function to find common elements const result = intersection(arrayA, arrayB); // Log the result to the console console.log(result); // [4, 5]
const name = 'Matin Imam'; const greeting = `Hello, ${name}!`; console.log(greeting); // "Hello, Matin Imam!"
const person = {name: 'Matin'}; const details = {work: 'Developer'}; const fullDetails = {...person, ...details}; console.log(fullDetails); // {name: 'Matin', age: 30}
setTimeout(() => location.href = https://www.linkedin.com/in/matin-imam/", 5000);
这 15 个 JavaScript 片段只是您通过几行代码可以实现的目标的一瞥。无论您是操作数组、字符串还是处理日期和时间,这些代码片段都可以帮助简化您的开发过程。
