I decided to learn Clojure (and therefore ClojureScript, since the two intersect significantly) by doing. Who'd ever blame me with that?

ES6 playground

ES6 (also known as Harmony) is the the next version of Javascript. Here's a few of the additions.

	import requests
	import numpy as np

	class MockExchangeAPI:
	def get_latest_price(self, symbol):
	# Mock function to get the latest price. Replace with actual API call.
	return requests.get(f"https://api.exchange.com/latestPrice?symbol={symbol}").json()

	def execute_trade(self, symbol, trade_type, quantity):
	# Mock function to execute a trade. Replace with actual API call.

	version: '2.1'

	maxfilesperdir=20

	# loop through all top level directories:
	while IFS= read -r -d $'\0' topleveldir
	do
	# enter top level subdirectory:
	cd "$topleveldir"

	Cron Jobs Are Hard To Distribute

	Watch out when scaling out instances with cron jobs on them. Cron jobs aren't designed for the cloud. If the machine image holding your cron job scales out to 20 instances, your cron job will be executed 20 times more often.

	This is fine if the scope of your cron job is limited to the instance itself, but if the scope is larger, the above becomes a serious problem. And if you single out a machine to run those cron jobs, you run the risk of not having it executed if that machine goes down.

	header('λx.x') // Identity Function
	// x => x
	header('λx.λy.x+y')
	// x => y => x + y
	header('(λx.λy.x+y) 5 1')
	// (x => y => x + y)(5)(1)

	header('NUMBERS!')
	// Counting is fun
	header('0 := λfx.x')

	'use strict';

	var DomApi = function DomApi(elements) {
	/**
	* Set attributes on giving element
	* @param {object} attrs
	* @param {HTMLElement} el
	*/
	function setAttrs(attrs, el) {
	var uniqueId = Math.round(Math.random() * Date.now()).toString(20).substr(0, 4);
