 What does `console` store?
 What does the syntax `console.log` or `console.assert` mean? In particular, what does the `.` mean?
+
+Step 1: Type console.log and hit Enter
+
+What you’ll see in Chrome’s Console:
+
+ƒ log() { [native code] }
+
+Meaning:
+This shows that console.log is a function, specifically one that’s built into the browser (that’s what “native code” means — it’s implemented in C++ within Chrome’s V8 engine, not in JavaScript itself).
+
+Step 2: Type just console and hit Enter
+
+What you’ll see:
+An object printed in the console — something like:
+
+Console {memory: MemoryInfo, debug: ƒ, error: ƒ, info: ƒ, log: ƒ, warn: ƒ, ...}
+
+
+Meaning:
+
+This shows that console is a built-in JavaScript object.
+
+It contains many methods (functions) such as:
+
+log() → prints messages
+
+error() → prints error messages (in red)
+
+warn() → prints warnings (in yellow)
+
+assert(), table(), clear(), etc.
+
+So you can think of console as a toolbox full of functions for logging and debugging.
+
+Step 3: Type typeof console
+
+Output:
+
+"object"
+
+Meaning:
+This confirms that console is an object in JavaScript.
+
+Now, answering the questions directly
+What does console store?
+
+console stores an object that provides access to a collection of built-in methods used for outputting information to the browser’s developer console.
+
+It’s part of the Web API — the environment provided by browsers, not part of the JavaScript language itself.
+
+What does the syntax console.log or console.assert mean?
+
+console.log means:
+
+Access the property named "log" inside the object named console.
+
+console.assert means:
+
+Access the property named "assert" inside the same object.
+
+In both cases, the property happens to store a function — so you can call it using parentheses, like console.log("Hi!").
+
+What does the . (dot) mean?
+
+The dot (.) is the property access operator in JavaScript.
+
+It’s used to access a property or method belonging to an object.
+
+In general:
+
+object.property
+
+means “get the value of property that belongs to object”.
+
+Examples:
+
+console.log    // accesses the log function in the console object
+Math.PI        // accesses the value of PI in the Math object
+document.body  // accesses the body element of the web page
