An "expression" is a phrase of #JavaScript that a JavaScript interpreter can evaluate to produce a value.
async function* nums() {
yield pFn1();
yield pFN2();
return 'yeah';
}
let itr = nums():
itr.next().then(log);
#javascript
async function user(id) {
if (await exist(id)) {
return await get(id);
} else {
return new Error();
}
}

"The only way to mutate the internal state is to dispatch an action."
#javascript #redux philosophy

let c = [];

ternaries in #react tends to be more confusing than helpful? I dunno
let someComponent = (bool) ? (<input />) : (<other />);
