我们需要编写一个 JavaScript 函数,该函数接收一个数字 n 作为输入,并找到前 n 个奇数自然数的平方和。例如:如果输入数字为 3。则输出将为:1^2 + 3^2 + 5^2 = 35因此,输出为:35示例以下为代码:const num = 3; const squaredSum = num => { let sum = 0; for(let i = 1; i
我们需要编写一个 JavaScript 函数,该函数接收一个数字作为输入并返回正好除以输入数字的数字的计数。例如:如果数字为 12,则其因数为:1、2、3、4、6、12因此,输出应为 6。示例以下为代码:const num = 12; const countFactors = num => { let count = 0; let flag = 2; while(flag
假设我们有一个 data.txt 文件,它与我们的 NodeJS 文件位于同一目录中。假设该文件的内容为:Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s.我们需要编写一个 JavaScript 函数来加载此外部... 阅读更多
我们需要编写一个 JavaScript 函数,该函数接收字符串作为输入并返回一个包含两个字符串值的数组,它们分别是字符串中最小和最大的单词。例如:如果字符串为:const str = "Hardships often prepare ordinary people for an extraordinary destiny";则输出应为:const output = ["an", "extraordinary"];因此,让我们为该函数编写代码示例以下为代码:const str = "Hardships often prepare ordinary people for an extraordinary destiny"; const largestSmallest = str => { const strArr = str.split(" "); let min = strArr[0]; let ... 阅读更多
