Reverse string using recursion in typescript

Ts program for Reverse string using recursion. Here problem description and explanation.

// Reverse string using recursion in TypeScript
class ReverseString
{
	// This is reversing the string elements recursively
	public string reverseText(text: string, location: number)
	{
		// Base condition to stop the recursion process
		if (location >= 0)
		{
			// Recursive function call
			return text.charAt(location) + 
              this.reverseText(text, location - 1);
		}
		// When no character remaining
		return "";
	}
	// This is handling the request process of reverse string elements
	public string reverse(text: string)
	{
		// Display given string elements
		console.log("Before Text : [" + text + "]");
		return this.reverseText(text, text.length - 1);
	}
	public static main(args: string[])
	{
		var task = new ReverseString();
		var text = "ABCDE";
		text = task.reverse(text);
		// After reverse	
		console.log("After Text  : [" + text + "]\n");
		text = task.reverse("654A321");
		// After reverse	
		console.log("After Text  : [" + text + "]\n");
	}
}
ReverseString.main([]);
/*
 file : code.ts
 tsc --target es6 code.ts
 node code.js
 */

Output

Before Text : [ABCDE]
After Text  : [EDCBA]

Before Text : [654A321]
After Text  : [123A456]
