+You can use `break` and `continue` in loops to alter the flow of the loop. `break` will stop the loop from continuing, and `continue` will skip the current iteration and continue the loop.
+
+```js
+for (let i = 0; i < 5; i++) {
+  if (i === 1) {
+    continue; // skips the rest of the code in the loop
+  }
+  console.log(`i: ${i}`);
+}
+
+// Output:
+// i: 0
+// i: 2
+// i: 3
+// i: 4
+```
+
+```js
+for (let i = 0; i < 5; i++) {
+  if (i === 1) {
+    break; // stops the loop
+  }
+  console.log(`i: ${i}`);

+Debugging JavaScript code can be achieved through various methods and tools. Here's a basic guide:
+
+## Console Logging:
+
+You can use `console.log()`, `console.warn()`, `console.error()`, etc., to print values, variables, or messages to the browser's developer console.
+
+```js
+console.log('Value of x:', x);
+```
+
+## Browser Developer Tools:
+
+Most modern browsers come equipped with developer tools. You can access these tools by pressing `F12` or right-clicking on the web page and selecting `Inspect` or `Inspect Element`.
+
+- **Sources Tab**: Allows you to see the loaded scripts, set breakpoints, and step through the code.
+- **Console Tab**: Displays console outputs and allows for interactive JavaScript execution.
+- **Network Tab**: Helps in checking network requests and responses.
+
+## Setting Breakpoints:
+
+In the `Sources` tab of the browser's developer tools, you can click on a line number to set a breakpoint. The code execution will pause at this line, allowing you to inspect variables, the call stack, and continue step-by-step.
+
+## Debugger Statement:
+
+Inserting the `debugger;` statement in your code will act as a breakpoint when the browser developer tools are open. Execution will pause at the `debugger;` line.
+
+```js
+function myFunction() {
+  debugger; // Execution will pause here when dev tools are open
+  // ... rest of the code
+}
+```
+
+## Call Stack and Scope:
+
+In the developer tools, when paused on a breakpoint or `debugger;` statement, you can inspect the `call stack` to see the sequence of function calls. The `Scope` panel will show you the values of local and global variables.
+
+Remember, debugging is an iterative process. It often involves setting breakpoints, checking variables, adjusting code, and re-running to ensure correctness.

+In order to parse JSON, you can use the `JSON.parse()` method. It parses a JSON string and returns the JavaScript equivalent.
+
+```js
+const json = '{"name":"JavaScript","year":1995}';
+const roadmap = JSON.parse(json);
+
+console.log(roadmap.name); // JavaScript

+In JavaScript, you can accept a variable number of arguments in a function using the `arguments` object or the rest parameter (`...`).
+
+## Using the `arguments` object:
+
+The `arguments` is an array-like object that holds all of the passed arguments. They are only available inside the function body.
+
+```js
+function displayArgs() {
+  for (let i = 0; i < arguments.length; i++) {
+    console.log(arguments[i]);
+  }
+}
+displayArgs(1, 2, 3, 4); // Outputs: 1, 2, 3, 4
+```
+
+## Using the rest parameter:
+
+The rest parameter allows you to represent an indefinite number of arguments as an array.
+
+```js
+function displayArgs(...args) {
+  args.forEach((arg) => console.log(arg));
+}
+displayArgs(1, 2, 3, 4); // Outputs: 1, 2, 3, 4
+```
+
+The rest parameter (`...args` in the example) is generally more modern and flexible, and it provides an actual array, unlike the array-like `arguments` object.

+    answer: In order to define multiline strings in JavaScript, you need to use template literals. Template literals are enclosed by the backtick (```` ` ` ````) character instead of double or single quotes. Template literals can contain placeholders. These are indicated by the dollar sign and curly braces (``` `${expression}` ```).
