Convert PascalCase, camelCase, snake_case, & kebab-case into "space case".

space-case.js

export const spaceCase = txtWithNoSpaces =>
	txtWithNoSpaces
		.split(/_|-/g) // snake_case & kebab-case
		.join(' ')
		.replace(/([A-Z])/g, ' $1') // PascalCase & camelCase
		.split(' ')
		.map(word => word.charAt(0).toUpperCase() + word.slice(1))
		.join(' ')
		.replace(/\s+/, ' ') // dashed entries create two spaces, bump that down to one
		.replace(/([A-Z])\s(?=[A-Z]\b)/g, '$1') // e.g. "U U I D" => "UUID"
		.trim()
