We passed a regular expression to the String.split() method. index.js function countWords(str) { return str.trim().split(/\s+/).length; } The forward slashes / / mark the beginning and end of the regular expression. The \s special character matches spaces, tabs and newlines. ...
If the input is a non-empty string, the function counts the occurrences of each character in the string using a 'Map' data structure. It iterates through each character in the string and updates the occurrence count in the Map. After counting the occurrences of each character, the function...
函数是 JavaScript 中的基本组件之一。JavaScript 中的函数类似于过程——一组执行任务或计算值的语句。但要成为函数,这个过程应该接受输入并返回与输入存在某些明显关系的输出。要使用一个函数,你必须将其定义在你希望调用它的作用域内。 参见JavaScript 函数的详细参考章节,以了解详情。
To count number of words in a string in JavaScript, split the string with all white space characters as a delimiter, remove the empty splits (empty strings in the array), and count the number of items in resulting array. The count must represent the number of words in the given string....
