Let’s say the following is our string −
var sentence = "My,,,,,,, Name,,,, is John ,,, Smith";
Use regular expression along with split() and join() to remove extra spaces and commas. Following is the code −
Example
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)
To run the above program, you need to use the following command −
node fileName.js.
Output
Here, my file name is demo133.js. This will produce the following output −
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
