I have been given the opportunity to review "Eloquent JavaScript" (3rd Edition) by Marijn Haverbeke, published by No Starch Press. First in the interest of fairness and openness; No Starch Press has very kindly sent me a copy of the book for free. As my regular readers may have noticed, I really enjoy the books … Continue reading Eloquent JavaScript -Book Review (JavaScript)
Over its lifetime JavaScript has increased the ways that variables can be declared.

My original Countdown blog post mentioned that the JavaScript could be used to update content on a webpage (e.g. the countdown could countdown in real time and update on a page as it does so). I touched upon a method to do this, however I will expand a little bit on it here: // writes … Continue reading Updating Web Text Content (JavaScript)
I am revisiting my JavaScript Countdown to turn elements of it into JavaScript functions. A function allows for parts of code to be reused easily without having to recreate the segment of code every time it is needed.

For more information on Blackjack please … Continue reading BlackJack Part 1 (JavaScript)
One of the earlier programs I wrote in Python was Scissor, Paper, Stone. It's an old game that most people learn as a child, the premise of which is; There are two (2) players.

JavaScript can be written in .js (JavaScript) files but can also be written directly into a web browsers JavaScript Console, which is a great way to see quick results from small bits of JavaScript coding. Today I will be looking at enabling the console within two browsers (Safari and Chrome). Safari To use the JavaScript … Continue reading Accessing A Browser’s JavaScript Console
