Ts program for Add two numbers using bitwise operators. Here problem description and explanation.

// TypeScript program for
// Add two numbers using of bitwise operators
class NumberAddition
{
	// Add two numbers
	public addition(a: number, b: number)
	{
		// Display given numbers
		console.log("\n [(" + a + ") + (" + b + ")] ");
		// Auxiliary variable which are store the carry bit result
		var carry = 0;
		// Executing loop, until b value is not zero
		while (b != 0)
		{
			// Get carry bits of a & b
			carry = a & b;
			// Sum of bits of a ^ b
			a = a ^ b;
			// Shift the carry bit by one bit in left side
			b = carry << 1;
		}
		// Display add result
		console.log("", a);
	}
	public static main(args: string[])
	{
		var task = new NumberAddition();
		// Test Case
		task.addition(8, -2);
		task.addition(5, 3);
		task.addition(-3, -5);
	}
}
NumberAddition.main([]);
/*
