Use the appropriate invocation syntax for functions based on their intended usage. Regular functions should be called directly without the `new` keyword, while constructor functions (typically capitalized) should be instantiated with `new`.

Incorrect:
// Using constructor syntax with a regular function
const context2 = new vm.createContext(context);
Correct:
// Calling a regular function properly
const context2 = vm.createContext(context);
// Using constructor syntax with an actual constructor
const myDate = new Date();
This distinction is important for code correctness and readability. Using new
with a non-constructor function can lead to unexpected behavior, while omitting new
when required can cause the function to execute in the global context instead of creating a new object instance.
