Triangle Walks This is one of my favourite songs from one of my favourite albums - Fever Ray by Fever Ray. I love it and it has a magical fairy tale vibe to it. I also like the feeling within it - "Who is that, to come by my house" - of setting a boundary. Rendering a Component's Props Continuing with yesterday's example  Also there's this bit as well...  Passing props From Component to Component "The most common use of props is to pass information to a component from a different component. Props in React travel in a one-way direction, from the top to bottom, parent to child." "Props passed down are immutable, meaning they cannot be changed. If a component wants new values for its props, it needs to rely on the parent component to pass it new ones." handleEvent, onEvent, and props.onEvent "When you pass an event handler as a prop, as you just did, there are two names that you have to choose. Both naming choices occur in the parent compon...

Halcyon and On and On and On and On and On and On and On and On and On I like this song.  It is the ending song to Mean Girls and the song at the beginning of the credits too and maybe even for all of the while credits. Regardless of whether it is for this reason or not, this song always makes me feel like I am having a happy ending. Here is a picture of my newt, lol Default Parameters "If a parameter is assigned a default value, TypeScript will infer the variable type to be the same as the default value's type. (This is similar to how TypeScript infers the type of an initialised variable to be the same as the type of its initial value)." "Parameters with default values don't need a ? after the name, since assigning a default value already implies that they're optional parameters". Inferring Return Types "TypeScript can also infer the types of values returned by functions.  It does this by looking at the types of the values after a function's r...
