Camel case is named after the "hump" of its protruding capital letter, similar to the hump of common camels.. Camel case (sometimes stylized autologically as camelCase or CamelCase, also known as camel caps or more formally as medial capitals) is the practice of writing phrases without spaces or punctuation and with capitalized words.
A sample of naming conventions set by Sun Microsystems are listed below, where a name in "CamelCase" is one composed of a number of words joined without spaces, with each word's -- excluding the first word's -- initial letter in capitals – for example "camelCase".
Underscores inserted between letters are very common to make a "multi-word" identifier in languages that cannot handle spaces in identifiers. This convention is known as "snake case" (the other popular method is called camelCase, where capital letters are used to show where the words start).
When Wikipedia was founded on January 15, 2001, it used the wiki engine UseModWiki, which only supported CamelCase links at that time. These links took the form of plaintext camelcase words, such as "WikiCase", and the displayed title of the page this linked to would split this text at each capital letter, producing "Wiki Case". [1]
Spaces and punctuation are removed and the first letter of each word is capitalised. If this includes the first letter of the first word (CamelCase, "PowerPoint", "TheQuick...", etc.), the case is sometimes called upper camel case (or, illustratively, CamelCase), Pascal case in reference to the Pascal programming language [29] or bumpy case.
One study has found that readers can recognize snake case values more quickly than camel case. However, "subjects were trained mainly in the underscore style", so the possibility of bias cannot be eliminated. [1] A variation is screaming snake case, where words are written in all caps (stylized as SCREAMING_SNAKE_CASE). [2]
The software treats all page titles as beginning with a capital letter (unless the first character is not a letter). For information on how to display article titles beginning with lower-case letters (as in eBay), or category titles (as in Category:macOS) see WP:Naming conventions (technical restrictions) § Lowercase first letter.
Wikipedia avoids unnecessary capitalization.In English, capitalization is primarily needed for proper names, acronyms, and for the first letter of a sentence. [a] Wikipedia relies on sources to determine what is conventionally capitalized; only words and phrases that are consistently capitalized in a substantial majority of independent, reliable sources are capitalized in Wikipedia.
