How Can I Convert Line Breaks to HTML `` Tags in JavaScript?

Converting Line Breaks to HTML Elements in JavaScript

In JavaScript, you can convert all line breaks within a string to HTML
elements using regular expressions. This is useful when you want to display multi-line text that maintains its formatting.

Implementation:

To replace all line breaks with
elements, use the following regular expression:

str.replace(/(?:\r\n|\r|\n)/g, '<br />');

Explanation:

• (?:rn|r|n): This matches all types of line breaks, including Windows (rn), Mac (r), and Linux (n).
• g: The g flag makes the replacement global, applying it to all occurrences of the line break.

Example:

Consider a variable str with the following value:

"This is man.

     Man like dog.
     Man like to drink.

     Man is the king."

After applying the replacement, the result will be:

"This is man<br /><br />Man like dog.<br />Man like to drink.<br /><br />Man is the king."

Non-Capturing Groups:

The ?: syntax surrounding the line break patterns creates a non-capturing group. This means that the line break characters are not captured into memory for later reference, which can improve performance for large strings.
