[Tools MarkDown] Create a Diff in Markdown to Show What Has Changed in a Code Snippet
ou can create diffs in markdown to show what has changed in a code snippet. I use this in blog posts to highlight changed lines for readers. This works for code snippets in most markdown packages and on Dev.to.
To show a line of code changing in a function, you can do this:
```diff function addTwoNumbers (num1, num2) { - return 1 + 2 + return num1 + num2 } ```
