Javascript's flexibility with optional parameters

Here's a function I'm working with:

public static async myFunc(
    x: 500,
    y: boolean = true,
    z = 1000,
)

I'm trying to invoke the function without supplying a value for y:

myFunc(1000, 2000);

However, I'm encountering an error stating that 2000 is not a boolean.

Answer №1

Have you considered implementing object destructuring in this way:

const myFunction = ({
    a = 10,
    b = false,
    c = 200,
})

Answer №2

Your function is designed to accept an object as a parameter.

const displayValues = ({ a, b, c }) => {
  console.log(a);
  console.log(b);
  console.log(c);
};

displayValues({ a: 700, b: true, c: "hello" });
