In order to make the program recognize the clicking of a button, the engineer should add an event listener to the JavaScript code.

An event is considered to be a vital part of JavaScript because a web page responds according to the event that occurred. Some events are generated by APIs and some are user-generated events. For example, clicking or moving the mouse button and pressing a key on the keyboard are user generated events.

In order to handle the user-generated events in JavaScript, an event listener is used. An event listener is a function or procedure in a JavaScript program that waits for an event to occur; such as pressing a key on the keyboard or clicking the button. Therefore based on the scenario given in the question statement, the engineer should use an event listener to his JavaScript code so that the code can recognize the click of the button.

Shtirlitz [24]

Answer:

Multimedia avenue.

Explanation:

A file type is the standard used to store data such as pictures, texts, videos, and audios. All file types have unique file extension that determine which program to use to open a particular file and to access its data e.g pictures (jpeg, png), texts (txt, docx, rtf), videos (mp4, 3gp, avi), audios (mp3, acc).

Sometimes, computer users make the mistake of opening files with the wrong software application or program, this often leads to an error due to the incompatibility of the software application with the particular file.

Basically, all software applications are designed and developed for use with specific file extensions or formats and as such, when used to open a file it isn't developed for, it result in an error.

A multimedia avenue refers to a channel that is designed and developed to accept, utilize and combine various file formats such as audio, video, text, animation effects, etc. A common example of a multimedia avenue is Microsoft PowerPoint software.

Hence, the multimedia avenue may utilize video streaming, audio narration, print designs and animation.
