Naming convention for const object keys in ES6

Question

Is there a recommended naming convention for key names within a const object in es6? I haven\'t been able to find a resource which states if they should be uppercase or lowercas

Answer 1

Naming conventions are all over the place, I personally still haven't decided on my preference but to add to the discussion this is what Airbnb JavaScript Style Guide says (see the last examples):

// bad
const PRIVATE_VARIABLE = 'should not be unnecessarily uppercased within a file';

// bad
export const THING_TO_BE_CHANGED = 'should obviously not be uppercased';

// bad
export let REASSIGNABLE_VARIABLE = 'do not use let with uppercase variables';

// ---

// allowed but does not supply semantic value
export const apiKey = 'SOMEKEY';

// better in most cases
export const API_KEY = 'SOMEKEY';

// ---

// bad - unnecessarily uppercases key while adding no semantic value
export const MAPPING = {
  KEY: 'value'
};

// good
export const MAPPING = {
  key: 'value'
};
