Benchmark: Object Lookup - MeasureThat.net

Script Preparation code:

var CONSTANTS = {
  codes: {
    error: {
      404: 'Not Found',
    },
    success: {
      200: 'Okay',
    },
  },
};

Tests:

Global
function global () { return { success : CONSTANTS.codes.success, error : CONSTANTS.codes.error, }; } global();
Local
function local (constants) { return { success : constants.codes.success, error : constants.codes.error, }; } local(CONSTANTS);
Destructuring Global
function destructuringGlobal () { const { success, error } = CONSTANTS.codes; return { success : success, error : error, }; } destructuringGlobal();
Destructuring Local
function destructuringLocal (constants) { const { success, error } = constants.codes; return { success : success, error : error, }; } destructuringLocal(CONSTANTS);
