假设以下是我们的字符串 −

var sentence = "My,,,,,,, Name,,,, is John ,,, Smith";

使用正则表达式以及 split() 和 join() 删除多余的空格和逗号。以下是代码 −

示例

var sentence = "My,,,,,,, Name,,,, is John ,,, Smith";
console.log("Before removing extra comma and space="+sentence);
sentence = sentence.split(/[\s,]+/).join();
console.log("After removing extra comma and space=");
console.log(sentence)

要运行上述程序,您需要使用以下命令 −

node fileName.js.

输出

此处,我的文件名为 demo133.js。这将产生以下输出 −

PS C:\Users\Amit\JavaScript-code> node demo133.js
Before removing extra comma and space=My,,,,,,, Name,,,, is John ,,, Smith
After removing extra comma and space=
My,Name,is,John,Smith
