In JavaScript, it provides for passing one value back to the code that called it after everything in the function that needs to run has finished running, and it passes a value from a function back to the code that called it by using the return statement and this value to be returned is specified in the return keyword. 

We will use the keys() method and the length property to count the number of keys in an object. We will use the object.keys() method's returns of an array for a given object's enumerable property names, that is, ["name", "age", "hobbies"]. The length property will help return the length of the array.values() Method: The Object.values() method returns an array of the object's enumerable property values. We should array the for-loop to get all the values of the object. A Dot Notation and a Bracket Notation in JavaScript can access an object value. To get the object value through a variable key, the value or expression inside the bracket notation must match the existing key name and then return a value. Unlike dot notation, bracket notation can be used with variables in JavaScript. 

Here is an example of how to retrieve number data from a JavaScript data object:

Fig : Preview of the output that you will get on running this code from your IDE.



Follow the steps carefully to get the output easily.

  1. Install JavaScript ES6 code snippet and Code Runner from Extension on your IDE(We use Visual Studio Code).
  2. Copy the snippet using the 'copy' and create one new file filename.js(eg.test.js) then paste the code in that JavaScript file.
  3. Save the file and run the file using run button to generate the output.

I hope you found this useful.

I found this code snippet by searching for 'How do I retrieve number data from a javascript data object' in kandi. You can try any such use case!

Environment Tested

I tested this solution in the following versions. Be mindful of changes when working with other versions.

  1. The solution is created and tested in Visual Studio Code 1.74.1.
  2. JavaScript ES6 Code Snippet version v1.8.0.
  3. Code Runner version v0.11.8.

Using this solution, we are able to retrieve number data from a javascript data object with simple steps. This process also facilities an easy way to use, hassle-free method to create a hands-on working version of code which would help us to retrieve number data from a javascript data object.
