issues accessing an array in an object jquery

Question

I am trying to access some data from an object as follows:

var summaryChanges = {
        dataToAdd:[
            {name:[]},
            {events:[]},
            {emails:[]}
        ],
        dataToRemove:[
            {name:[]},
            {events:[]},
            {emails:[]}
            ]
  }

i am trying to log the contents of the name property of data to add as follows:

console.log($(summaryChanges.dataToAdd.name)[0]);

however the console only logs undefined.

DataToAdd is an array, so you should access it as such. You can use dataToAdd[0] to do so. — Cereal

dataToAdd is an arrary not an object , so access it like

console.log(summaryChanges.dataToAdd[0].name[0])

Thanks that fixed it, still getting used to syntax of objects etc, much appreciated

how would I format the object so as to be able to access checkpoints as a key (I read that js doesn't do associative arrays) ie summaryChanges.dataToAdd.name[i]

Figured it out,: var summaryChanges = { dataToAdd:{ checkpoints:[], events:[], emails:[] }, dataToRemove:{ checkpoints:[], events:[], emails:[] } }

You need to realize some things

$(summaryChanges.dataToAdd.name) you are creating a jQuery Object.
summaryChanges it's an object so you can do sumaryChanges.dataToAdd
dataToAdd it's an array, so for get a value you access it like this dataToAdd[index]

At the end you access it like this

console.log(summaryChanges.dataToAdd[index].name[index])
