#!/bin/bash

# This script, executed at the root of a git repository, deletes traces of every old file in this repository, index + blob on all branches
# It can take 10-30 minutes to run and will print regular warning stating than some references are unchanged
# time ./clear_git_repositor.bash >cleaning.log 

# We need several passes to clean files renamed multiple times (git log --find-renames prevents its deletion for each renaming)
# MAXIMUM_PASSES should be more than the maximum number of renamings/movings for any file, if not then we might keep some traces of former files
MAXIMUM_PASSES=10  # Maximum number of passes

Frontend interview questions

General

• What Javascript Frameworks do you know? Which one do you like? Why?
• What is the atomic design?

Coined by Brad Frost, Atomic Design is a methodology that involves breaking a website layout down into its basic components, which are then reused throughout the site. You have Atoms => Molecules => Organisms => Templates => Pages.

• Can you name two programming paradigms important for JavaScript app developers?

set -e, -u, -o, -x pipefail

The set lines

• These lines deliberately cause your script to fail. Wait, what? Believe me, this is a good thing.
• With these settings, certain common errors will cause the script to immediately fail, explicitly and loudly. Otherwise, you can get hidden bugs that are discovered only when they blow up in production.

• set -euxo pipefail is short for:

set -e
