The HTMLAudioElement interface provides access to audio> element properties as well as methods for manipulating them.
It is based on the HTMLMediaElement interface.
The Audio() function Object() { [native code] } accepts any file type that contains audio to be played as a parameter.

We refer to JavaScript as obtrusive when the amount of code is so large that it effectively obscures the HTML.
Unobtrusive JavaScript, on the other hand, is a best practise methodology for attaching JavaScript to the front-end of a website.

Gecko is the name given to the Mozilla Project's layout engine.
Gecko was created at Netscape before the Mozilla Project was formed in 1997 as the successor to the original Netscape rendering engine.

The audio tag includes methods such as play(), pause(), and so on./p>

shadowBlur is used to determine whether shadows are crisp or fuzzy. The blur level for shadows is set or returned by the shadowBlur property.

The colour, gradient, or pattern used to fill the drawing is set or returned by the fillStyle property.
The strokeStyle property sets or returns the stroke colour, gradient, or pattern.
The canvas object does not have a property called lineSize.

It is in charge of displaying the web page.
The rendering engine parses the HTML and CSS and displays the content that has been parsed on the screen.
A Rendering Engine is commonly used to parse and draw all of the objects on a page.

The toPrecision() method formats a number to the length specified.
To create the specified length, a decimal point and nulls are added (if necessary).

The code snippet creates an HTML paragraph element with an id of "demo". A function named "myFunction" is defined. Inside this function, a variable named "num" is declared and assigned the value of 13.3714.

The next line uses the DOM method "getElementById" to access the element with the id of "demo" and assigns its innerHTML the value of the "num" variable passed through the "toPrecision()" method. The "toPrecision()" method is a built-in JavaScript function that rounds a number to a specified number of digits. In this case, it is set to 3, so the number 13.3714 will be rounded to 13.4 and displayed inside the "demo" paragraph element.

When the function is called, it will execute these statements and display the rounded number on the webpage.

SVG is an abbreviation for 'Scalable Vector Graphics,' which is used to define graphics for the Web.
SVG is primarily used for vector diagrams such as two-dimensional graphs in an X, Y coordinate system, pie charts, and so on.
Complex shapes are described by SVG as a "path" of lines and curves that can be drawn or filled.

The code snippet you provided is a simple JavaScript function called "myFunction". This function performs the following actions:

1. The first line inside the function declares a variable called "num" and assigns it the value of the result of the mathematical expression 3 + 2, which is 5.

2. The next line declares a variable called "n" and assigns it the value of the primitive value of the "num" variable by calling the valueOf() method.

3. The final line uses the JavaScript DOM method getElementById() to select the HTML element with the id "demo" and then sets the innerHTML property of that element to the value of the "n" variable.

4. The function does not call itself and it need to call it to execute the code, for example myFunction()

In this case, when the function is called it will select the HTML element with the id "demo" and set its innerHTML to the value of the variable "n", which is 5. So, the output will be 5 in the element with id "demo" on the web page.
