Mini template engine in JavaScript

	/**
	* Mini template engine. Parses variables (w/o dot notation) and does not delete undefined variable expressions.
	* @param {string} expr - String expression with {{variables}} to interpolate.
	* @param {RegExp} [regex] - Custom regex to match variables. By default it matches double curly braces `{{variables}}`.
	* @returns {(data:Object\|string[]) => void} - A function that accepts an object or an array as argument to interpolate the template variables.
	* @example
	* const templateObj = parseTemplate('{{a}} {{b.c}}');
	* template({a: 'hello', b: {c:'world'}}); // "hello world"
	*
	* const templateArr = parseTemplate('{{}} {{}}');
