Problems you may face

1. While running eslint fix on the project i got this error

AssertionError [ERR_ASSERTION]: Node must be provided when reporting error if location is not provided

to fix it i did a loop on the files in the directory and fix each of them to get the code snippet that cause the previous problem

for file in *; do                                            
    if [ -f "$file" ]; then
        ../node_modules/eslint/bin/eslint.js "$file" --fix
    fi
done
