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 <h2> 08. 将数字数组转换为<a style="color:#f60; text-decoration:underline;" href="https://www.php.cn/zt/52359.html" target="_blank">字符串数组</a> </h2> <pre class="brush:php;toolbar:false">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功能的一瞥。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。
