In this short instructional video, the speaker demonstrates four practical ways to leverage JavaScript within the n8n workflow automation platform. First, they show how JavaScript can clean and structure unstructured data, correcting spacing, phone number formats, and email capitalization. Second, they illustrate filtering order records by criteria such as amount > 100 and region not equal to EU. Third, they simplify messy API responses into a tidy JSON structure. Fourth, they perform financial calculations—tax rate, total tax, profit, margin, and margin percent—based on supplied inputs. The speaker admits limited JavaScript proficiency and recommends using ChatGPT to generate the needed code by providing contextual prompts. Finally, they promote their "NAN" community where they teach all things related to n8n.

Here's 4 ways to use JavaScript in N8N. By the way, JavaScript is the most underrated node. So we can give an input that looks like this with unstructured data. You can see there's a space after the dough, the phone number is unstructured, and there's a capital letter where there shouldn't be in the email. And then we can run it through JavaScript and get an output that looks like this with structured data. Or we could use it for filtering by giving it order information like this and then filtering on specific criteria and then giving us that information back. In this case, it was if the amount is more than 100 and the region was not EU. We can use it to simplify messy API responses so they look like this and then get turned into this. Or we can use it for calculations by giving it inputs like this and then having an output like this. You can see it's calculated the tax rate, the total tax, the total profit, the margin, and then the margin percent. And just a disclaimer, I don't even know how to code JavaScript. I've got no idea how to write it. I understand the basics, but pretty much I should get ChatGPT to generate all of my JavaScript. Literally just give it context on what I want and then it just outputs the JavaScript for me. By the way, I'm building the best NAN community where I teach all things NAN. So
