This JavaScript code snippet is designed to prevent runts in HTML text elements. A runt is a single word on the last line of a paragraph, which can be visually unappealing. The code targets all HTML elements with the class .no-runt and modifies their text content to ensure that the last line contains at least two words.
The code operates as follows:
- It selects all elements with the class .no-runt.
- For each selected element, it splits the text content into an array of words.
- If the element contains more than one word, it appends the last word to the second-to-last word, separated by a non-breaking space ( ). This effectively joins the last two words together, ensuring they will appear on the same line.
- It then removes the last word from the array (since it has already been appended to the previous word).
- Finally, it joins the modified array of words back into a single string and sets it as the new HTML content of the element.
This approach ensures that no selected text element ends with a single word on its last line, thus enhancing the typographic appearance of text-heavy web pages.
