Search through an array of objects and assign a new value

I am facing a challenge with an array of objects structured as shown below:

[
    {
        "e_id": "1",
        "total": 0
    },
    {
        "e_id": "3",
        "total": 0
    }
]

My objective is to increment the total value in a forEach loop based on the e_id. I have attempted the following approach:

e.forEach((row) => {
    this.arrayObj[row.e_id]['total']++;
});

Unfortunately, this method does not seem to be effective because it seems to use the e_id as an index rather than a reference. Any idea how to make this work?

Answer №1

data=[
    {
        "id": "A1",
        "amount": 0
    },
    {
        "id": "B3",
        "amount": 0
    }
]

data.forEach((item) => {
    item['amount']++;
});

Is this information necessary?
