I have an object which looks as below. It can have any number of Array object each representing count of ErrorType.
data =
{
"1": [
{
"ErrorType": "Error-1A",
"Error": "Wrong Password for 1A"
},
{
"ErrorType": "Error-1B",
"Error": "Host not matching"
}
],
"2": [
{
"ErrorType": "Error-2A",
"Error": "Wrong User for 1A"
},
{
"ErrorType": "Error-2B",
"Error": "connectivity issue"
}
],
"3": [
{
"ErrorType": "Error-3A",
"Error": "Wrong version"
}
],
"16": [
{
"ErrorType": "Error-4A",
"Error": "Unknown"
}
]
...
...
}
I want to capture all the count values and push them in an array countArray in descending order.
countArray = [16, 3, 2, 2, 1, 1];
I want to capture the corresponding ErrorType and push them in an array errorTypeArray.
errorTypeArray = ['Error-4A', 'Error-3A', 'Error-2B', 'Error-2A', 'Error-1B', 'Error-1A'];
I have written the following code so far but it is not complete:
const countArray = [];
const count = Object.keys(data).length;
for ( let i = 0; i < count; i++) {
countArray.push(data[i]);
}

If you do not need to match the key to the ErrorType, then this will work:
const data = { "1": [ { "ErrorType": "Error-1A", "Error": "Wrong Password for 1A" }, { "ErrorType": "Error-1B", "Error": "Host not matching" } ], "2": [ { "ErrorType": "Error-2A", "Error": "Wrong User for 1A" }, { "ErrorType": "Error-2B", "Error": "connectivity issue" } ], "3": [ { "ErrorType": "Error-3A", "Error": "Wrong version" } ], "16": [ { "ErrorType": "Error-4A", "Error": "Unknown" } ] };
let errorArray = [];
const countArray = Object.keys(data).reduce((acc, key) => { // run over the keys
data[key].forEach(item => {
errorArray.push(item.ErrorType); // save the errortype
acc.push(key); // save the key as many times as there are items in the array
});
return acc;
}, [])
.sort((a, b) => b - a);
errorArray.reverse()
console.log(countArray)
console.log(errorArray)
