JavaScript creating an array from JSON data?

To create an array from JSON data, use the concept of map() from JavaScript. Let’s say the following is our data −

const studentDetails =[
   {
      name : "John"
   },
   {
      name : "David"
   },
   {
      name : "Bob"
   }
];

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.

Output

This will produce the following output −

PS C:\Users\Amit\JavaScript-code> node demo82.js
[ 'John', 'David', 'Bob']
