10 Mostly used HTML Symbols

Anna — Sat, 12 Jun 2021 20:49:28 +0000

Writing the copyright sign in html using entity name as © or using number-code as © to easily display © made sense to me.

Little did I know that empty-space( ), slash sign ( | ), or even a dash ( - ), also hold special code in html. Similarly for a ‘ or an “.

Think about '<' being used as a 'less-than' symbol. HTML would render text after 'less-than' symbol as the beginning of a tag name, thus would create confusion. Bad character error would be avoided if you write:
 4 is < than 3  or:
 4 is < than 3 
instead of:  4 is < than 3 

There is a case where in styling, you would want your web layout to be consistent. Say, a paragraph  some text  in section-1 has some text, and similar paragraph in section-2 has no text. Instead of living the p tag empty as , you could use an empty space symbol ( ), and write it in deci-code as:
  or in hex-code as &#x20

Maybe you are using AZERTY keyboard and you don't want to spend your time figuring out where the back-tick is, just use ` .

After coding a couple of pages, I made a list for quick referencing the html symbols, their number-code/hex-code and entity code for the ones I have mostly used in basic web-pages. See cover image of this article for the list

I would substitute those characters in the html and use number code, hexadecimal or their entity names instead.

Example on how to use the symbols in code:

wow! to wow&excl;

You can get more of these symbols from W3. There is also a nice table here. Maybe an official one is your preference

Now, you are probably asking what is html-entity. Here is an MDN explanation

Which symbol have you used the most so far, and is not included in this list? Please add in the discussion section below…

Unary operators in Javascript Objects

Anna — Thu, 23 Jul 2020 13:18:04 +0000

A unary operator is an operation with only one operand.

Plus sign (+) can function as an Addition Operator and also as a Unary Version in Javascript Objects.

As an arithmetic addition operator: It takes numerical values (literals or variables) as their operands and return a single numerical value.

Both + and - operators have unary versions, where they operate only on one variable.
When used in this fashion, + returns the number representation of the object, while - returns its negative counterpart

The unary plus operator converts its operand to Number type.

The unary negation operator converts its operand to Number type and then negates it.
