What was your last mistake as a Programmer?

I think that all newcomers need to hear that all developers make mistakes. They should not worry about this, but if possible fix their mistakes and learn from them.

I'll start with my last mistake done today. I'm Web Developer working with JavaScript. I've created a PR with small change that was reviewed and in one of the comment fellow developer added a comment about one function. I've planed to use that function in two places, but decided to delete that other place, after CR I've added that code back but with a bug that throw error when deploy to our dev environment.

The code looked like this:

import { scoreValue } from '../../../../utils/scoreValue'

when I first added this code, before I deleted the code, got error that scoreValue was already defined so I've changed the code to:

import { scoreValue as calculateScoreValue } from '../../../../utils/scoreValue'

and it was working. The problem was that after CR when I added that change back I forget that renaming of the variable and it thrown an error when building the project.

Our PM (Project Manager) that trigger deploy (yes I know this should be CI/CD) written on our group chat that the build was failing. I quickly fix the issue and this time he did the CR (because my colleague was not available at this moment) and the fix was done.

Luckily I don't have any issues with production environment, and this was just minor problem that was fixed quickly. But it was my mistake that I did. This should not happen I should check local build. We have live reload in the project and the error was in the console.
