Parameters:
Name Type Attributes Description
obj * <optional>
<repeatable>

Arguments to Object.assign()
Returns:

An object with no prototype, having ...obj properties

Type
Object

(static) defineConstants() → {Object}

Create a read-only map-like object.
This differs from createMap only in that the argument must be non-empty, because the result is frozen.

Returns:
Type
function
