The find() method will return the value of the first element in an array which will pass a given test.

The find() method will execute a function for each array element, returning undefined if no elements are found. The major difference between the map find is that the map() goes through all entries. Then creates a new array using the function supplied, whereas find() locates a specific entry by a predicate and returns it. Both are legitimate in that both methods are supposed to do.

Reduce() method is nothing, but it applies a function simultaneously against two array values from left to right to reduce it to a single value. Also, it executes a user-supplied reducer callback function on each element of the array. It will then pass in the return value from the calculation on the initial elements in JavaScript. A single value is a final result of running the reducer across all the array elements, and it does not execute the function for empty array elements. It does not change the original array.

Here is an example of how the find method can be achieved through reduce method in ES6:

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 Visual Studio Code on your computer.
  2. Download JavaScript(ES) Code snippet and Code Runner from extension.
  3. Create a new folder in your local.
  4. Open that folder in Visual Studio Code.
  5. Then create a new JS file(Eg: Test.js).
  6. Copy the snippet using 'copy' button and paste it into that file.
  7. Save and run the file using run button.

Note: Remove last two lines of code after pasting the snippet.

I hope you found this helpful.

I found this code snippet by searching for 'es6 find method can be achieved through reduce method' 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 v1.8.0.
  3. Code Runner v0.12.0.

Using this solution, we are able to achieve find method through reduce method in ES6 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 achieve find method through reduce method in ES6.
