Q:

How can remove keys with empty values in an Object Array in TypeScript?

I'm trying to write a function in my Angular 8 project. I have an Array of Objects and want to remove all key:value pairs where the value is empty. There are many examples on the internet but none of them seem to work for me.
What I have:
{
        "flightID": "FooID",
        "direction": "DownFoo",
        "msgType": "FooType",
        "elemNb": "",
        "msgID": "",
    },
    {
        "flightID": "FooID2",
        "direction": "UpFoo",
        "msgType": "FooType2",
        "elemNb": "",
        "msgID": "",
    },

What I want: 
    {
        "flightID": "FooID",
        "direction": "DownFoo",
        "msgType": "FooType",
    },
    {
        "flightID": "FooID2",
        "direction": "UpFoo",
        "msgType": "FooType2",
    },

My attempt:
myList: any[]

 removeEmptyValues() {
    if (this.myList) {

      this.myList.forEach((value) => {

        Object.keys(value).forEach((key) => {
          delete key[''];

        })
      })
    }
    console.log(this.myList);
  }

I would expect that delete key[''] would delete the key if the value is empty but it isn't doing anything. How can I delete the key if the value is empty?

A:

Try deleting value[key] instead of key['']
if (value[key] === '') {
  delete value[key];
}
