An Introduction to HTML: The Programming Language for Creating Web Pages

M Fariz Wisnu prananda — Fri, 16 Dec 2022 10:32:09 +0000

HTML, which stands for HyperText Markup Language, is a programming language used to create and structure content on the World Wide Web. It is the standard markup language for creating web pages and is used to describe the structure and formatting of a document written in HTML.

HTML consists of a series of elements, or tags, that are used to define the content and structure of a web page. These elements include headings, paragraphs, lists, links, and more. HTML also allows for the use of multimedia, such as images and videos, and can be used to create interactive forms and other interactive elements.

To create an HTML document, you can use a simple text editor like Notepad or TextEdit. The document must be saved with the .html file extension in order for it to be recognized as an HTML document by a web browser.

To add content to an HTML document, you can use various tags, such as the

tag to define a paragraph, the

tag to define a heading, and the tag to create a hyperlink. HTML also includes tags for formatting text, such as bold and italic, and for creating lists, tables, and forms.
HTML also allows for the use of Cascading Style Sheets (CSS) to define the style and layout of a web page. By using CSS, you can control the font, color, and layout of your web page, making it easier to create a consistent look and feel across multiple pages.

In addition to being used for creating web pages, HTML is also used to create email messages and mobile applications. It is an essential skill for anyone looking to work in web design or development, and it is a fundamental building block of the World Wide Web.

Variable on Golang

M Fariz Wisnu prananda — Sat, 30 Oct 2021 04:49:36 +0000

so now i will tell about variable in golang.

in golang, when the variable declaration must be followed by its data type. this concept is manifest typing . an example like this

package main

import "fmt"

func main(){
   var firstName string = "Sakura "
   var lastName string
   lastName = "endo"

   fmt.Printf("halo %s %s!\n", firstName, lastName)
}

the result is

like the code above, I write down the variable followed by the name and data type

How to declare variable using var

conditions in variable declaration with var like this

Declaration without value

var <name-variable> <type-data>

2.Declaration with value

var <name-variable> <type-data> = <value>

Example

var Name string
var Hobby string = "Football"

What is the use of "fmt.Printf()" ?

the function is the same as Println, but the output is defined at the beginning, in the "hello %s %s!\n" section, %s will be replaced with a string where the string is filled with the value of the 2nd to 3rd parameter and so onof the parameter.

fmt.Printf("Hi %s %s", firstname,lastname)
fmt.Printf("Hi "+  firstname + lastname + "!")

in addition to using "%s" to connect between strings, you can also use "+" .this is called string concatenation

Multi-variable declaration

This way, we can declare multiple variables with just 1 line.
Example:

var firts,second,third string
firsts,second, third = "1","2","3"

easy and very simple,could be more concise this way

var firts,second,third string = "1","2","3"

firts,second,third := "1","2","3"

End
