Remove extra spaces in string JavaScript?

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
