Namespaces

Like TypeScript, a namespace is used for logical grouping of functionalities.
A namespace can include interfaces, classes, functions and variables to support a single or a group of related functionalities.

syntax

namespace varname {
...statements
}

export

Entities declared inside a namespace aren't accessible externaly unless they are exported.

examples

namespace Util {
	func reverse(value: String): String => value.split('').reverse().join('')
	func reverse(value: Array): Array => value.slice().reverse()

	export reverse
}

const foo = Util.reverse('hello')

namespace Waldo {
	export class Foobar {
		private {
			_name: String
		}
		constructor(@name = 'john')
	}
}

const x = new Waldo.Foobar()

namespace Foobar {
	export const PI = 3.14
	export const name = 'john'
}

console.log(Foobar.PI)
console.log(`\(Foobar.name)`)
