Question
How does the trim() function modify a JavaScript string?
Solution
The trim() function in JavaScript is used to remove whitespace from both ends of a string. Here's how it works:
-
First, you need to have a string. For example, let's say we have the following string: var str = " Hello, World! ";
-
To remove the whitespace from both ends of this string, you would use the trim() function like this: var trimmedStr = str.trim();
-
Now, the variable trimmedStr contains the string "Hello, World!" without any leading or trailing whitespace.
It's important to note that the trim() function does not modify the original string. Instead, it returns a new string that has been trimmed of leading and trailing whitespace.
