Tests:

  • lodash.each

     
    _.each(obj, function(v, k) {})

  • lodash.map

     
    _.map(obj, function(v, k) {})

  • Object.entries.map

     
    Object.entries(obj).map(function([k, v]) {})

  • vanilla for-loop w/ Object.entries

     
    const entries = Object.entries(obj);
    for (let i = 0; i < entries.length; i++) { const [k, v] = entries[i]; }

  • lodash.forEach

     
    _.forEach(obj, function(v, k) {})

  • Object.values

     
    const entries = Object.values(obj);
    for (let i = 0; i < entries.length; i++) { const v = entries[i]; }

  • Object.keys

     
    const entries = Object.keys(obj);
    for (let i = 0; i < entries.length; i++) { const [k, v] = entries[i]; }
