Guide on accessing the value within an array located inside an object

Hello everyone, I'm new to Angular and I need some help accessing the values inside objects. Specifically, I'm trying to access the SuccessCount in this Array.

Here is my attempt:

goodResponse=[
    {compId: 1, companyName: "A", pendingCount: 0, successCount: 0, apiErrorCount: 0, …},
    {compId: 1, companyName: "B", pendingCount: 0, successCount: 0, apiErrorCount: 0, …},
    {compId: 3, companyName: "C", pendingCount: 0, successCount: 0, apiErrorCount: 0, …},
    {compId: 4, companyName: "D", pendingCount: 0, successCount: 0, apiErrorCount: 0, …}
]

let _graphTotal = this.goodResponse;
let _graphTotalCount = []
_graphTotal.forEach(element => {
   console.log("total Count", element[0].successCount)
});

Answer №1

When utilizing a ForEach loop, remember that each "element" represents a data point within the array. Therefore, you must access it like this:

element.successCount

Answer №2

When looping through the goodResponse array, make sure to access the object within it by utilizing the following code snippet:

goodResponse.forEach(item => {
   console.log("Success Count:", item.successCount)
});

Answer №3

Instead of attempting to access a non-existent element of successCount, make sure to access the successCount of the current element.

_graphTotal.forEach(item => {
   console.log("total Count", item.successCount)
});

Answer №4

Substitute element[0].successCount with element.successCount.

Answer №5

When using map, each element returned will be an object. This means that the first element returned by map corresponds to the 0th index of the array. You will then have an object as your first element, requiring you to use a dot (.) to access its contents. This is why the function becomes element.successCount.
