The key-events happen whenever a user interacts with keyboard. There are mainly three key event types − keydown, keypress and keyup. This event fires when the user releases the key.
My conclusion is ‘event’is a reserved word which stands for event argument in Java Script.
What are all the key event listeners?
- keydown : Keydown happens when the key is pressed down, and auto repeats if the key is pressed down for long.
- keypress : This event is fired when an alphabetic, numeric, or punctuation key is pressed down.
- keyup : Keyup happens when the key is released.
What is a key event?
An event which indicates that a keystroke occurred in a component. This low-level event is generated by a component object (such as a text field) when a key is pressed, released, or typed.
The event loop is a constantly running process that monitors both the callback queue and the call stack. If the call stack is not empty, the event loop waits until it is empty and places the next function from the callback queue to the call stack.
