I am looking to enhance my JSON data by including a key-value pair in each object within the array.

My goal is to insert a key-value pair into every object in the students array.
To achieve the desired result, follow these steps:
const details = [ { city: 'New York', company: '123'}, { city: 'Chicago', company: '456'}, { city: 'London', company: '789'}];
details.forEach((item) => {
item['email']= '<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="84e5e6e7c4fcfdfeaae7ebe9">[email protected]</a>';
console.log(item);
});
// Display the final result
console.log(details);One approach could be to utilize a for loop to iterate through each element in the array, and since it's in JSON format, you can simply add a new "key = value" pair inside each current element.
For example:
var companies = [
{id: 33, uuid: "3d103130-ae0d-11e9-8e6c-dfb1a3a5afce", name: "test", address: "test", city: "tes" },
{id: 34, uuid: "81524090-ae0d-11e9-8894-2326c7695f11", name: "test2", address: "test2", city: "test2"}];
for (let i = 0; i < companies.length; i++) {
companies[i].key = "value";
}
To begin, start by cycling through the array of students using either a foreach loop or a standard for loop. This will allow you to access each student individually. Since each student is represented as an object, you'll need to use either dot notation or bracket notation to add this new key-value pair. For guidance on choosing between these methods, check out this informative article: Bracket notation vs Dot notation
Note: Be aware that if the key you are adding already exists, the previous value will be replaced.
For loop
for (let i = 0; i < students.length; i++) {
const student = students[i];
student[<key>] = <value>;
}
Foreach
students.forEach(student => {
student[<key>] = <value>;
});
