Checking for the presence of the key name "item[]" within an object in AngularJs

I currently have an object called "obj" with two keys: "goal" and "item[]". It looks like this:

var obj = {goal:"abc",item[]:"def"};

These keys and values are dynamically generated.

Now here's the problem -

I need to determine if these keys exist in the object. If I use the code

if(obj.goal != undefined){
   //Do something
}

it works as expected. However, if I try

if(obj.item[] != undefined){
  //Do something
}

I encounter a syntax error. Can someone please advise on how to check for the second case? Thank you in advance.

Answer №1

It is recommended to utilize bracket notation in the following way:

if (obj['item[]'] !== undefined) {
