HTML Links

• HTML links are hyperlinks.

You can click on a link and jump to another document.

HTML Links - Syntax

The HTML <a> tag defines a hyperlink. It has the following syntax:

<a href="url">link text</a>

The most important attribute of the
<a>
  element is the href attribute, which indicates the link's destination. The
  link text is the part that will be visible to the reader.
</a>

Email Links

HTML
<a>
  tag provides you option to specify an email address to send an email. While
  using
  <a>
    tag as an email tag, you will use mailto: email address along with href
    attribute. Following is the syntax of using mailto instead of using http.
    example <a href="mailto: abc@example.com">Send Email</a></a
  ></a
>

• <header> - Defines a header for a document or a section
• <nav> - Defines a set of navigation links
• <section> - Defines a section in a document
• <article> - Defines an independent, self-contained content
• <aside> - Defines content aside from the content (like a sidebar)

• <footer> - Defines a footer for a document or a section

• <details> - Defines additional details that the user can open and close on demand

• <summary> - Defines a heading for the <details> element

Functions is js

A function in JavaScript is similar to a procedure a set of statements that performs a task or calculates a value, but for a procedure to qualify as a function, it should take some input and return an output where there is some obvious relationship between the input and the output.

• To use a function, you must define it somewhere in the scope from which you wish to call it.

Defining functions

• The name of the function.
• A list of parameters to the function, enclosed in parentheses and separated by commas.
• The JavaScript statements that define the function, enclosed in curly brackets, {…}.

For example

function square(number) {
return number \* number;
}

Control flow

The control flow is the order in which the computer executes. Code is run in order from the first line in the file to the last line

A typical script in JavaScript or PHP (and the like) includes many control structures, including conditionals, loops and functions. Parts of a script may also be set to execute when events occur.

JavaScript Operators

* let x = 5; // assign the value 5 to x * let y = 2; // assign the value 2 to y
* let z = x + y; // assign the value 7 to z (5 + 2)
