Hi Geraldo, The only special merging behavior is in the rules section of the config. Every other object (settings, parserOptions, etc.) effectively worked by using Object.assign() where the first objects are the ones from the configs you're extending and the last is your .eslintrc.* file.
As such, it's not possible to clear all settings. You can clear an individual setting key by assigning it to null. It is not possible to modify the value of a settings key, so no, it's not possible to just remove ".jsx" from the array. You'd have to completely overwrite the array with just what you want. I hope this helps.
