pseudosavant / alternate-for.js
Created October 21, 2022 18:02
Simple JavaScript for loops
// Alternate for loop that is more of a functional style
// `fr` accepts two arguments.
// The first argument expects an Array (to get the length of it) or a number. Passing in an array is similar to `myArray.forEach()`.
// The second argument is a function with the signature `(currentIteration, totalIterations)`
const fr = (iterationsOrArray, fn) => {
if (typeof iterationsOrArray !== 'number'&& !Array.isArray(iterationsOrArray)) {
throw new TypeError('Invalid argument: expected an `Array` or `number` for the first argument');
}
let iterations = (Array.isArray(iterationsOrArray) ? iterationsOrArray.length : iterationsOrArray);

Roku devices can be easily controlled via an HTTP API. It is accessed by issuing a POST request to http://{device_ip}:8060/keypress/{command}.

[NOTE: it must be accessed by IP address only and not hostname due to how Roku handled addressing a DNS Rebinding vulenerability.][1]

Created October 17, 2019 18:02
Convert strings or object keys from underscore_naming to camelCaseNaming. Example here: https://glitch.com/edit/#!/camelize
function camelize(s) {
return s.replace(/(?:-|_)([a-z])/g, (c) => c[1].toUpperCase());
}
function camelizeObjectKeys(o) {
const entries = Object.entries(o);
const output = {};
entries.forEach(([key, value]) => output[camelize(key)] = value);
