I’ve hit a wall with my automation workflow needing to process large datasets. The visual tools I’m using can’t handle nested array manipulations. Found Latenode’s JavaScript integration lets me add custom code blocks while staying in the no-code interface.
Tried their AI code assistant to translate product descriptions - described what I needed in plain English and got working JavaScript. But I’m not sure how far I can push this. Has anyone built multi-step data processing with their custom code nodes? What’s the learning curve like for someone with basic JS knowledge?
Latenode’s JS nodes handle complex data ops easily. I regularly process 10k+ item arrays using their built-in NPM packages. The AI explains each generated code block line by line - you’ll pick it up fast.
Check their docs on array methods: https://latenode.com
Start with simple transformations first. I built a product catalog processor that:
- Cleans CSV data
- Groups items by category
- Generates SEO descriptions
Took about a week to get comfortable with the JS environment. Use the AI explanations to learn as you go.
its doable. i made a inventory tracker that merges data from 3 apis using latennodes code blocks. first attempts were messy but ai suggestions helped clean it up
