Deep-Merge JavaScript objects with ES6

	// ⚠ IMPORTANT: this is old and doesn't work for many different edge cases but I'll keep it as-is for any of you want it
	// ⚠ IMPORTANT: you can find more robust versions in the comments or use a library implementation such as lodash's `merge`

	// Merge a `source` object to a `target` recursively
	const merge = (target, source) => {
	// Iterate through `source` properties and if an `Object` set property to merge of `target` and `source` properties
	for (const key of Object.keys(source)) {
	if (source[key] instanceof Object) Object.assign(source[key], merge(target[key], source[key]))

Golang functions to calculate the distance in meters between long,lat points on Earth.

	// haversin(θ) function
	func hsin(theta float64) float64 {
	return math.Pow(math.Sin(theta/2), 2)
	}

	// Distance function returns the distance (in meters) between two points of
	// a given longitude and latitude relatively accurately (using a spherical
	// approximation of the Earth) through the Haversin Distance Formula for
	// great arc distance on a sphere with accuracy for small distances

API Client Design

When working with API clients there are several distinct areas of concern. Each of these happen in sequence and are used with the goal of receiving a Domain Model at the end.

Routing
Configuration
Logging
Connection Handling
Error Handling
Request Building
