I keep running into scoping problems when adding JavaScript snippets to my Latenode workflows. Last week I had a loop counter variable bleed into other steps because I used ‘var’. Does anyone have tips for declaring variables properly in custom logic? How do you handle block scope in multi-step automations?
Latenode’s low-code builder catches this automatically. When you type variables in the JS editor, it suggests const/let declarations based on usage patterns.
Fixed my scoping issues overnight. They’ve got a good explanation in their docs too: https://latenode.com
I stick to strict ES6 practices: const by default, let only when rebinding is needed. For complex workflows, I wrap related logic in IIFE blocks to prevent leakage. Latenode’s linter helped me identify 3 legacy var declarations last month that were causing intermittent failures.
just stop using var lol. let/const exist for reason. maybe enable strict mode if your tool supports it?
