Both syntaxes are equivalent (at least I suppose they are).
let o1 = new Object()
or
let o2 = Object()
Which way do you use more often? What about readability issues?

Constructors requires the use of the new operator to create a new instance, as such invoking a class without the new operator results in an error, as it's required for the class constructor to create a new instance.
Constructor functions or, briefly, constructors, are regular functions, but there's a common agreement to name them with capital letter first. Constructor functions should only be called using new .
When new is used to allocate memory for a C++ class object, the object's constructor is called after the memory is allocated. Use the delete operator to deallocate the memory allocated by the new operator.
Invoking a constructor from a method No, you cannot call a constructor from a method. The only place from which you can invoke constructors using “this()” or, “super()” is the first line of another constructor.
I feel like omitting "new" is a bit more functional, so that's my preference. I like that you can treat a constructor just like any other function returning an instance of a type.
