JavaScript Syntax Mocktest

The 'constructor' method in a JavaScript class is used to initialize the class properties when new instances of the class are created. It is automatically called when you create a new object from the class. Therefore, option B, 'To initialize class properties', is correct for explaining the purpose of the 'constructor' method in a JavaScript class.

Option A correctly declares a JavaScript module with a named export 'myFunc' using the 'export' keyword followed by a function declaration. This is the ES6 syntax for exporting functions, variables, or objects from a module. Options B, C, and D use different syntaxes that are not specific to JavaScript modules. Therefore, option A is the correct way to declare a JavaScript module with a named export.
