How to remove a character from key of array of objects in javascript? [duplicate]

Question

I have a javascript object as follows:

result = [
   {"Account_ID__r.Name":"Yahoo Inc Taiwan","Contact_ID__r.Email":"[email protected]"},
   {"Account_ID__r.Name":"WXIA-TV","Contact_ID__r.Email":"[email protected]"}
]

I need to remove the period(.) from the keys of the object. (Example: The key Account_ID__r.Name should become Account_ID__rName)

The above array should become as follows:

result = [
   {"Account_ID__rName":"Yahoo Inc Taiwan","Contact_ID__rEmail":"[email protected]"},
   {"Account_ID__rName":"WXIA-TV","Contact_ID__rEmail":"[email protected]"}
]

I tried to construct a new array by using for (var key of Object.keys(result)) { } but it didn't work.

Code that I tried:

result.forEach(item => {
                    for (var key of Object.keys(item)) {
                        var keyWithoutPeriod = key.replace(/\./g,'');
                        this.datatableData.push({
                            [keyWithoutPeriod]: item[key] 
                        });
                    }
                });

It converted the code as follows:

datatable = [
   {"Account_ID__rName":"Yahoo Inc Taiwan"},{"Contact_ID__rEmail":"[email protected]"},
   {"Account_ID__rName":"WXIA-TV"},{"Contact_ID__rEmail":"[email protected]"}
]

This is not in the format that I need. Please help. Thank You😃.

In your code, replace this.datatableData.push() line with item[keyWithoutPeriod] = item[key]; delete item[key] — adiga

You could get entries, replace unwanted characters and build new objects.

const
    data = [
        { "Account_ID__r.Name": "Yahoo Inc Taiwan", "Contact_ID__r.Email": "[email protected]" },
        { "Account_ID__r.Name": "WXIA-TV", "Contact_ID__r.Email": "[email protected]" }
    ],
    result = data.map(o => Object.fromEntries(Object.entries(o).map(([k, v]) => [k.replace(/\./, ''), v])));

console.log(result);
