1. How do you think the javascript is lightweight?
I list some of key characteristics about Javascript is a lightweight programming language:

Fast execution – JavaScript’s interpreted feature, allowing it runs directly in browsers without needing a separate compilation step, making execution quick and efficient.
Minimal resource demands – JavaScript operates in a single-threaded environment, reducing memory consumption and avoiding the overhead of multi-threaded switching.
Browser friendly – JavaScript doesn’t need additional installations or complex runtimes; it executes directly within web browsers, making it lightweight for client-side applications.

Despite the JavaScript is a lightweight language, it remains the powerful with optimizations like JIT compilation and modern browser engines.

2. How do you think of the javascript’s dynamic feature

JavaScript’s dynamic features are a key part of its flexibility and power, here are something relate to its dynamics:

Variables in JavaScript don’t have to define explicit type declarations, which making it easier and faster to write the code, the data types were determined at runtime, it provides the developer handling the data conveniently.
The Object manipulation in JavaScript is dynamic, we can update the Objects at runtime, including add, remove and modify the properties and methods in the Objects, it provides great dynamics and interactive when we are developing our web applications.
Event-driven programming, JavaScript is a single-threaded programming language, so it adopted the event-driven programming style to deal with the actions, so it’s good at responding the events like click, keyboard, form submission, which make it great ability to create interactive and user-friendly web pages without refresh our webpages

So, those show JavaScript’s dynamic features, and make it really powerful for building modern web applications.
