React keys are useful when working with dynamically created components or when your lists are altered by the users. Setting the key value will keep your components uniquely identified after the change.

Using Keys

The Random Code Generator. This website can generate batches of up to 250,000 unique random codes at a time. Not logged in, it's limited to 1000 codes per batch. If you own a Random Code Generator account, it can generate an unlimited amount of codes in batches of 250.000 each! The generated codes can be used as random promotional codes, serial numbers, strong passwords, sweepstake codes.

User can himself define the range like i did in this tutorial and the number will only be generated between given range. Contents in this project Generate Random Number Between 1 to 100 in React Native: 1.

The Wireshark WPA Pre-shared Key Generator provides an easy way to convert a WPA passphrase and SSID to the 256-bit pre-shared ('raw') key used for key derivation.

App.jsx

main.js

Generate A Random Unique Key Reaction

We will get the following result for the Key values of each element.

Foreign Key

If we add or remove some elements in the future or change the order of the dynamically created elements, React will use the key values to keep track of each element.
