alert user in javascript

To display a simple alert message to the user in JavaScript, you can use the alert() function.

Here's an example:

index.tsx
alert("Hello, World!");
24 chars
2 lines

When this code is executed, it will display a pop-up window with the message "Hello, World!". You can replace "Hello, World!" with any message or variable that you want to display to the user.

Keep in mind that the alert() function will block the execution of the script until the user closes the alert window. It is mainly used for simple notifications or debugging purposes. For more advanced or interactive user interface elements, you may want to consider using other methods or libraries.
