What is the process for removing a specific column (identified by its key value) from a JSON table using JavaScript and Typescript?

[{
    "name": "employeeOne",
    "age": 22,
    "position": "UI",
    "city": "Chennai"
},
{
    "name": "employeeTwo",
    "age": 23,
    "position": "UI",
    "city": "Bangalore"
}
]

If I remove the "Position" key and value from the JSON, the updated result will be:

[{
    "name": "employeeOne",
    "age": 22,
    "city": "Chennai"
}, {
    "name": "employeeTwo",
    "age": 23,
    "city": "Bangalore"
}]

Suppose we have a list of employees in a table and I want to delete only the position column for all employees. How can this be achieved using JavaScript and TypeScript?

I attempted:

const output = delete employee.position

but encountered an error.

Within this collection are numerous objects. Your task is to iterate through each object, removing the specific property within them one by one.

Answer №3

check out the remove operation

algorithm:

for each item in recordArray
{
remove item["location"];
}

it also functions with:

item[location]
item.location
