title: Symbols date: 2021 Oct 10 --- In our lifes on the internet, we see alot of characters that we don't normally see. Like @, #, &amp;, [], {}, \, ;, and |. But what are thier names, what are their origins, and why do they look like they do? I'm going to try and find out!Let's start with what they are used for most of the time on the web.@ is used to mean at. It can also be used to define a username(bold"@user), or even emails(personbold"@emailprovider.topleveldomain)The hashtag, #, is used for tagging posts to topics(bold"#NumberOneProgrammer). It is also sometimes used to define a number(bold"#1). It's also used in CSS to define IDs, and in urls to scroll down to a certain part of the page(bold"#theMan).&amp; is a symbol used to mean "and"(the dog bold"&amp; the cat). It is also used in urls to be an addition to the search(?q=look%20mom%20no%hands%21bold"&amp;images)Square brackets([]), are used to define a list in the most widely used programming language on the web, JavaScript(bold"["the dog", "the cat", "the bird", "the plane"bold"]). They can also be used in the middle of quotes to give context("Have a nice day!" bold"[The mayorbold"] shouted)Curly brackets({}) are used to define a JavaScript object( {person: "Jim", car: "JavaScript car :)"} )backslash(\) is used in markdown, and JavaScript strings, to define a character that should remain itself, such as bold"\# showing up as a # instead of a heading.Semi-collins(;) are used to define the end of a command in lots of programming languages, like JavaScript(alert("hello world")bold";), PHP(echo "hello world"bold";)|, or Vertical bar, has no real use on the web.~, or tilde, also, doesn't find much useGrave accents() are used to define a multi-lined JavaScript string(<span style="font-weight:bold">this has2 linesbold"</span>)</li></ol>Those are what they are, but what about their original meanings?<ol><li>The At-Sign(@) is used to mean at(they're <span style="font-weight:bold">@</span> their house), it could also be used for a price(<span style="font-weight:bold">@</span>10 pence)</li><li>#(pound-sign, hashtag, number-sign, octothorpe, sharp-sign), it's used to mean lb(10 <span style="font-weight:bold">#</span>), define numbers(<span style="font-weight:bold">#</span>10), define a tag in social media(<span style="font-weight:bold">#</span>NumberOneCoder), to define the musical notes that are sharp, or used on telephones to do... something.</li><li>Ampersands(&amp;) are used as &amp;, that's it(doges <span style="font-weight:bold">&amp;</span> golden retrievers).</li><li>[Square Brackets] are used as a way to add context to the middle of a sentence, like "he ate the sausage", but we don't know who "he" is, and what kind of sausage he is eating, so it should be "<span style="font-weight:bold">[the young boy]</span> ate the <span style="font-weight:bold">[cheese filled]</span> sausage"</li><li>{Curly Brackets} don't get much use.
