add TypeScript

[aqandrew]

custom objects like notes, measures, and durations are unwieldy

[bEluga0000]

can u please explain what the issues is .

[aqandrew]

Sure. In reducers.js, there are some object definitions that represent tracks, measures, durations, and notes:

fret-zone/src/reducers.js

Lines 3 to 44 in 423cf94

	export const initialAppState = {
	selectedTrackNumber: 0,
	selectedMeasureNumber: 0,
	selectedDurationId: undefined,
	selectedStringNumber: 0,
	// https://redux.js.org/recipes/structuring-reducers/normalizing-state-shape
	tracks: {
	byId: {},
	allIds: [],
	},
	measures: {
	byId: {},
	allIds: [],
	},
	durations: {
	byId: {},
	allIds: [],
	},
	notes: {
	byId: {},
	allIds: [],
	},
	};
	export const defaultMeasureOptions = {
	timeSignature: {
	beatsPerMeasure: 4,
	beatUnit: 4,
	},
	keySignature: {
	tonic: 'C',
	isMajor: true,
	},
	durations: [],
	};
	export const defaultDurationOptions = {
	isRest: false,
	length: 1 / 4,
	isDotted: false,
	notes: [],
	};

I'd like to add TypeScript to this project so that I can have more confidence in manipulating these object properties. I also find VS Code's Intellisense for TypeScript very helpful.

okay i will try to move this project to typescript

[aqandrew]

Please don't do that. For the time being this is just an educational project for myself, so I'm not accepting unsolicited PRs

[bEluga0000]

okay
