Javascript coding guidelines

These are listed in no particular order, but are numbered so they can referenced more easily.

1. No interface should accept data that is not necessary for it to do its job. "Interface" includes: HTTP APIs (e.g. REST), function & method signatures, and React Component props, among others.
2. Functions and methods should never mutate their arguments. Avoid patterns that rely on mutation of arguments.
3. Prefer "flatter" codepaths. Nesting lots of if / else statements is hard to follow and re-organize. Bail early using return instead of nesting subsequent code.
4. Prefer flat data structures instead of deeply nested objects.
5. If the majority of a routine is inside a loop, extract the core of the loop into a separate routine that operates on a single item.
6. Extract magic strings and numbers from logic. At minimum, they should be declared as constants at the top of the file that uses them. Ideally, constants that influence observable behavior should be provided by a const

// Step 1: open somafm player
// Step 2: click "Favorite Songs"
// Step 3: drag-select all the text from the first song title to shopping cart on last row
// Step 4: copy & paste that text into text2tsv in JS console
// Step 5: paste result into Google Docs and you have a spreadsheet

const text2tsv = (text) => text.split('\n\n \n')
.map( r => r.trim().split('\n\n') )
.map( t => ({ artist: String(t[0]).trim(), title: String(t[1]).trim() }) )
.map( t => `${t.artist}\t${t.title}` )

one of those moments of programming eloquence you hope for, discovered to be unneeded immediately upon finishing it

the final code:

handleWordClick = (word, event) => {
	let isShiftClick = (this.state.shiftActive);
	let [ hasClickFn , hasShiftClickFn ] = [ 'onClick', 'onShiftClick' ].map((p) => (typeof this.props[p] === 'function'));
