Fetch specific values from array of objects in JavaScript?
Let’s say the following are our array of objects:
const details = [ { employeeFirstName: "John", employeeLastName: "Doe" }, { employeeFirstName: "David", employeeLastName: "Miller" }, { employeeFirstName: "John", employeeLastName: "Smith" } ]
Example
Following is the code to fetch specific values, in this case with first name “John” −
const details = [ { employeeFirstName: "John", employeeLastName: "Doe" }, { employeeFirstName: "David", employeeLastName: "Miller" }, { employeeFirstName: "John", employeeLastName: "Smith" } ] for (var index = 0; index < details.length; index++) { if (details[index].employeeFirstName === "John") { console.log("FirstName=" + details[index].employeeFirstName + " LastName= " + details[index].employeeLastName); } }
To run the above program, you need to use the following command −
node fileName.js.
Here, my file name is demo223.js.
Output
The output is as follows −
PS C:\Users\Amit\JavaScript-code> node demo223.js FirstName=John LastName= Doe FirstName=John LastName= Smith
