   • https://auth0.com/blog/a-brief-history-of-javascript
2. keywords: var, let, const, function, typeof

3. what is window object in JavaScript
   • https://www.w3schools.com/js/js_window.asp
4. window.document, DOM basics

5. console(window object), some console functions: console.log, console.warn, console.error, etc.

6. data types and data structures.

• Primitives: string ,number, boolean, undefined, null(null type is object, null is a global object)
• Complex: object ,array (array type is object, Array is a global object, represents indexed collection), function (function has it's own type, but it's a fundamental object too)
