Language Fluency

The relevant languages for this course are Python and JavaScript. Language fluency is basically knowing what to write to get the program to do what we want, or else knowing where to look it up. In this course, the focus was on writing your own code. Therefore, you don’t need to master every detail of both languages upfront. Here are some lists of topics that suffice for basic fluency.

JavaScript

The version of JavaScript used in this course is called JSX. It combines JavaScript 6, which is also known asEC- MAScript 6 with component creation shortcuts. It still uses the core JavaScript language. We should know:

• JavaScript’s var for defining variables as well as const for immutable and let for mutable data from JSX, and variable scope.
• Working with strings, numbers, arrays, and objects, and also using their methods.
• JSX object destructuring, for example, const {x} = some_obj;.
• Using conditionals (if-else) and program flow (for, do-while, while).
