Function Multiple arguments in TypeScript

In TypeScript, we can use multiple arguments in a method or function by specifying the type of each argument separated by a comma.

Here is an example of a function with two arguments:

function addNumbers(num1: number, num2: number): number {
  return num1 + num2;
}
let sum = addNumbers(10, 20);

console.log(sum); //Output: 30

In the above code, we have a function named addNumbers that takes two arguments, both of type number. The function then returns the sum of these two numbers.

To use this function, we simply call it with two arguments (10 and 20) and store the returned value in a variable named sum.

We can define functions with more than two parameters as well. Here is an example:

function printDetails(name: string, age: number, email: string): void {
  console.log(Name: ${name}, Age: ${age}, Email: ${email});
}
printDetails("John", 25, "john@example.com");

In this example, we have a function named printDetails that takes three arguments - name of type string, age of type number, and email of type string. The function logs the details to the console when called.

To use this function, we simply call it with three arguments - the name, age, and email of the person we want to print the details of.
