JavaScript: Basic Functions and Examples

JavaScript is a syntax language used in basic web design that primarily handles interactive elements and dynamic functions. It is often used to supplement the core HTML files supplying the basic structure and text content of web pages alongside CSS files that dictate those pages' aesthetic themes, but the functionality it provides is closer to traditional software programming. Modernized JavaScript is powerful and intuitive enough that it does not necessarily take many lines of code to create a process that is essentially a fully functioning browser-based game.

A website located at slicker.me provides a page that hosts an entirely functional recreation of the classic puzzle video game Minesweeper created entirely out of JavaScript code. It is presented as an example for a tutorial on basic JavaScript functionality and shows that it does not take much more than one hundred distinct lines of code to emulate the rules of the game and render it compatible with mouse cursors and clicks. An "init" function is used to dynamically generate a board with a width of twenty tiles and a height of four tiles. Just like in the source material, clicking on any given hidden tile on the board may either clear away a large swath of the overall board or instantly end the player's session on account of having clicked on an unfortunately placed bomb. The simulation even supports marking tiles with flag icons using the right mouse button.

How each individual function interacts with each other is visually laid out in an "algorithm" chart image that shows what specific functions should be called when a covered tile is clicked and the type of tile it represents is unveiled. The portion of the chart that is encased in a "Reveal" label is the location of a function that calls itself repeatedly so that all contiguous empty spaces connected to the clicked space will be simultaneously revealed if the clicked space does not contain a mine. The JavaScript process involves creating arrays that include a full set of previously created image files representing the different types of tiles used in Minesweeper.
