The good part: This is dynamic, emerging platform that facilitates learning and sharing, minimizing (some of) the heartache of learning HTML/CSS and Javascript. It also allows us to observe a community as it is forming, to observe that community figure out its own norms, objectives, users, and limits. Not to mention the chance to participate in that community. The downside: This platform is emerging and somewhat baroque to navigate. User-contributed questions and answers, on the site and offsite, tend toward experienced users--please don't let this disuade you! The best tip we have is to make liberal use of the on the right. It is beyond the scope of this short workshop to do much more than scratch the surface, but if you are unfamiliar, we hope you have a chance to explore the excellent training materials linked to below. - [A Taste of Observable](https://observablehq.com/@observablehq/a-taste-of-observable) (high level intro to the ecosystem) - [Learning Observable Notebooks and Cells](https://observablehq.com/@observablehq/learning-observable-notebooks-and-cells) - [Observable Documentation](https://observablehq.com/@observablehq/documentation) - [Observable's Observable Account Collections](https://observablehq.com/@observablehq) > ↑ Check out this page for great curated collections of notebooks.`32:T490,{ // Note: when working with a JavaScript cell, any line like this that is preceded by // and is greyed out is a comment // Look to these as tips or instructions on how to work with this particular cell // Let's play with the various ways to change the output of a JavaScript function. // (1) Change the text below and press `play` to the right (to execute the code). let objectTitle = "What is the title?";
