Examples of How The Dot Is Used
In web development languages such as HTML, CSS, JavaScript etc., the dot operator is a common syntax character that serves as a delimiter when declaring objects/variables/functions from classes or external libraries. For instance: if we have an external JavaScript library called 'lib' with a function called 'init()', then we would use '.lib.init()' to reference it within our web page codebase. In terms of file systems like UNIX-based platforms (Mac/Linux), dots are used to denote hidden files with special functions which are otherwise inaccessible without certain commands being issued beforehand by the user at the command line interface or terminal window. Additionally, dots are used within Unix-based commands such as 'ls -a', which lists all folders and files stored in a directory - including hidden ones beginning with '.' Henceforth these operators are also referred to as dot-files/dot-directories respectively through this method of denotation.
