To remove extra spaces, you need to use trim() along with regular expressions. Following is our string with spaces before applying trim() −
var sentence="My name is John Smith ";

var sentence="My name is John Smith "; console.log("The actual value="); console.log(sentence); var originalSentence = sentence.replace(/\s+/g,'').trim(); var afterRemovingTheSpace=originalSentence.trim(); console.log("After removing the spaces="); console.log(afterRemovingTheSpace);
To run the above program, you need to use the following command −
Here, my file name is demo90.js.
This will produce the following output −
