The regular expression should match all whitespace characters, and you can replace them with an empty string to remove them.
const text = " This is a text with spaces, tabs,\nand line breaks. "; const trimmedText = text.replace(/\s+/g, ""); console.log(trimmedText);
In this program, we define a variable called text that contains the text we want to process.
We then use the replace() method to remove all whitespace characters from the text.
The regular expression \s+ matches one or more whitespace characters, and the g flag tells replace() to replace all occurrences of the pattern in the string.
We replace the whitespace characters with an empty string “”, effectively removing them from the text. Finally, we log the resulting text to the console.
When you run this program, you should see the following output:
As you can see, all whitespace characters have been removed from the original text.
