How to multiply two integers represented as strings and return the result also as a string in TypeScript

Answer 1

function multiplyStrings(num1: string, num2: string): string {
    // Convert strings to integers
    const n1: number = parseInt(num1, 10);
    const n2: number = parseInt(num2, 10);

    // Perform multiplication
    const result: number = n1 * n2;

    // Convert result back to string
    return result.toString();
}

const num1 = "123";
const num2 = "456";

console.log("Result: " + multiplyStrings(num1, num2));



/*
run:

"Result: 56088"
