Kata

Create two variables of type number for working with assignment operators

    var a: number = 10;
    var b: number = 5;

Output to the console the results of assignment operators (=, +=, -=, *=, /=, %=)

    var a: number = 10;
    var b: number = 5;
    var result: number = 0;

    result = a + b;
    console.log('result = a + b; // result =' + result);

    result += a;
    console.log('result += a; // result =' + result);

    result -= a;
    console.log('result -= a; // result =' + result);

    result *= 2;
    console.log('result *= 2; // result =' + result);

    result /= a;
    console.log('result /= a; // result =' + result);

    result %= 2;
    console.log('result %= 2; // result =' + result);
