Hello there new programmer! If you've never programmed before, you're in for a treat because this is the section for you! In this section we're going to be covering the very basics of JavaScript from the ground up. Welcome new programmer, to a whole world of wonder… These are the fundamentals that you will need to know to do the fancy schmancy stuff that you're probably quite keen to get started on shortly. We'll be creating some fun little programs, making some sandwiches, and learning a little (or a lot) along the way. If you're already a ninja coder, you have a different set of challenges ahead of you. Javascript is rather different to what you might be used to. If you've used a language with C based syntax before, such as Java, you might feel lulled into a false sense of security by the similarities, but don't be fooled, under the hood, JavaScript is a different sort of animal.ĭo feel free to skim. You should check out functions though as these are a little different from what you may be used to. You might find you have to unlearn a few things along the way.

Note shinyjs must be initialized with a call to useShinyjs () in the app's ui.

In this exercise, we'll be saying hello to JavaScript. 1 runjs (code) Arguments code JavaScript code to run.
Of course the JavaScript won't actually hear us saying hello, unless we shout really loud… Create some HTMLįirst of all we'll need to make a web page for our script to live in. Create the following ultra simple html document and save it in a folder. Call it hello.html.Įither way I would alert some kittens.
Variables can be called almost anything you like.
Hamster, pie or cheeseOnToast are all perfectly sound variable names. The one restriction is that you can't have any spaces or maths characters in them. You can't have a variable called "cheese on toast" for instance, or a variable called five+five.
