Naming convention for const object keys in ES6

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 lowercase.

const COLOR_CODES = {
  BLUE: 1,
  RED: 1
};

vs

const COLOR_CODES = {
  blue: 1,
  red: 1
};

The examples from this MDN article show both styles, so maybe both are acceptable.

Solution

  • According to Google it would be all caps. Speaking from experience, most of the other programming languages have all caps so I would suggest using that.

    Use NAMES_LIKE_THIS for constant values.

    Use @const to indicate a constant (non-overwritable) pointer (a variable or property).
