There are other keyboard events which are almost like JavaScript keycodes with very little differences namely KeyboardEvent key property, Keyboard event with char property and keyboardEvent which property.

All the browsers present are almost compatible with the JavaScript keycodes with certain exception where the browser support is bit less or if there exist some incompatibility issues.

The syntax flow is in a way which very uniquely represents the keycode with event which is event.keycode.

Any number representing a Unicode character code or Unicode key code is used as a return type.

In case it is pretty much needed to know which kind of key press is responsible for event occurred with ALT then altkey is used, CTRL is used with ctrlkey, META is used with metakey and shift is used with shiftkey property.

To make the web browser support compatible this keycode and which property is used in unison to resolve the compatibility and version issues.

The keycode property is a read only method property which do not support for any write property to intervene the entire process.

In case there is a need to convert the final Unicode character then, its pretty much a need to use the fromCharCode() method.

To support for a cross-browser solution which property together with keycode needs to check.

The keycode property does not work seamlessly with the onkeypress event while using a web browser for Firefox.

Consider an example where the character has value with lower case and the equivalent character value is also same which signifies a fact that in both the condition key pressed will be same therefore the keycode needs to find a difference which can include the fact with a difference in the ASCII character and the keycode related to the Unicast character. But the exception arises with a fact that these two types of Character code and keycodes are not responsible for following the process of representation in a similar format.On the other hand, keycodes as part of JavaScript is mainly used to represent number in with an actual key on the keyboard.Character codes as part of JavaScript keycodes is mainly used to represent number in an ASCII format for characters.There are mainly two types of keycodes namely character codes and keycodes.To elaborate the process properly following is the working flow for keycodes in JavaScript which are as follows: Web development, programming languages, Software testing & others
