React Js get key of selected value from Dropdown
React Js get key of selected value from Dropdown:In Reactjs, to get the key of the selected value from a Dropdown component, you need to assign each option in the Dropdown a unique key-value pair, typically using an array of objects. When the user selects an option, you can access its key using the event handler. For example, you can use the "onChange" event and access the selected option's key like this:
event.target.value. Make sure to map the options with unique keys, allowing you to retrieve the selected option's key for further processing in your application.

How can I retrieve the key associated with the selected value from a Dropdown component in Reactjs?
This Reactjs code creates a dropdown (select) element with options. When a user selects an option, the key of the selected value is retrieved and displayed in the console. The selected option's key is found by matching the selected value with the corresponding object in the options array. The code uses React's useState hook to manage the selectedOption state. When the user changes the dropdown value, the handleDropdownChange function is called to update the selectedOption state and find the selected option's key.
