How to Convert JavaScript Multi-Line Strings to Single-Line with Tabs

If you are working with JavaScript, you may occasionally encounter the need to transform a multi-line string into a single-line string. This includes properly placing line breaks (\n) and tab indentations (\t). While there is plenty of information available on adding line breaks, the topic of tab support can be a bit trickier. This guide will guide you through a straightforward approach to achieve that.

The Problem at Hand

Consider this multi-line string in JavaScript:

This conversion needs to replace indentation spaces with tabs and retain the necessary line breaks while removing undesired tags.

The Solution

We can tackle this problem using the .replace() method in JavaScript, which allows us to perform search-and-replace operations on strings. Below are detailed steps to achieve the desired transformation.

Step 1: Replace Spaces with Tabs

To switch from spaces to tabs, we can identify 4 spaces which indicate a tab in our context. Using a regular expression, we can look for these spaces and replace them with a \t (tab character).

Step 2: Remove Unwanted Tags

Next, you need to get rid of the HTML tags (<code> and </code>) from the string. To do this, another .replace() operation will remove these tags entirely, ensuring a cleaner output.

Step 3: Replace New Lines with Line Breaks

Finally, we replace any newline characters (i.e., line breaks) in the string with '\n' in order to retain the structure you want in the single-line format.

Complete Code Implementation

Here’s how the complete code would look, integrating all the points mentioned:
