How to pass an object to a JavaScript function?

To pass an object to a JavaScript function, we can add a parameter that accepts an object.

For instance, we write

const someFunc = (arg) => {
  alert(arg.foo);
  alert(arg.bar);
};

someFunc({ foo: "This", bar: "works!" });

to define the someFunc function that takes the arg object argument.

Then we get the properties with arg.foo and arg.bar.

Next we call someFunc with an object with the properties.
