Following is the code to create an array from the above data −
Example
const studentDetails =[ { name : "John" }, { name : "David" }, { name : "Bob" } ]; const ListOfStudentName = studentDetails.map(({name:actualValue})=>actualValue); console.log(ListOfStudentName);
To run the above program, you need to use the following command −
node fileName.js.
Here, my file name is demo82.js.

This will produce the following output −
PS C:\Users\Amit\JavaScript-code> node demo82.js [ 'John', 'David', 'Bob']
