Every N8N JavaScript Function Explained (106 + 7 Extras)

One of the greatest parts about N8N is your ability to use JavaScript in the 'expression' field and your code editor. Compared to other no‑code tools, this opens up a world of possibilities, but because it's code‑adjacent it can be difficult to get up and running without coding knowledge. In this video I will methodically go through every single built‑in N8N JavaScript function, including string manipulation like 'includes()' and 'replaceAll()', to number and array functions like 'append()', 'map()', and 'reduce()'. I’ll also walk you through a couple of real‑world applications using base64 encoding, website scraping, HTML tag stripping, and datetime management. The video covers topics from 00:00:00 to 01:57:19, including the Edit Fields Node at 00:02:45 and the conclusion at 01:57:19.
