node js get list of all names of object array

To get a list of all names from an object array in Node.js, you can follow these steps:

1. First, define your object array. For example, let's say we have an array called myArray that contains objects with a name property:

const myArray = [
  { name: 'John' },
  { name: 'Sarah' },
  { name: 'Michael' },
];

1. Next, use the map() function to iterate over each object in the array and extract the name property. This will create a new array with just the names:

const namesArray = myArray.map(obj => obj.name);

1. The map() function takes a callback function as an argument. In this case, the callback function takes each object obj in the array and returns only the name property.

2. Finally, you can access the namesArray, which contains all the names from the original object array:

console.log(namesArray); // Output: ['John', 'Sarah', 'Michael']

In summary, the above steps demonstrate how to use Node.js to extract all the names from an object array. By utilizing the map() function, we can iterate over each object and retrieve the desired property, resulting in a new array that contains only the names.
