What is the best way to initialize a JavaScript Date to midnight?

Question

What is the simplest way to obtain an instance of new Date() but set the time at midnight?

Answer 1

A one-liner for object configs:

new Date(new Date().setHours(0,0,0,0));

When creating an element:

dateFieldConfig = {
      name: "mydate",
      value: new Date(new Date().setHours(0, 0, 0, 0)),
}
