Remove extra spaces in string JavaScript?

JavascriptWeb DevelopmentObject Oriented Programming

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 ";

Now, we will remove the extra spaces as in the below code −

Example

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 −

node fileName.js.

Here, my file name is demo90.js.

Output

This will produce the following output −

PS C:\Users\Amit\JavaScript-code> node demo90.js
The actual value=
My name is John Smith
After removing the spaces=
MynameisJohnSmith
