Tesla Coding Interview Questions for JavaScript 

1. What is the difference between Java and JavaScript?

Despite sharing a similar name, Java and JavaScript fundamentally differ in their design, purpose, and application. Java is an object-oriented programming language primarily used for building standalone applications, mobile apps, and large-scale backend systems. Java applications are typically compiled into bytecode, which the JVM executes on the target machine.

In contrast, JavaScript is a lightweight scripting language that helps add interactivity to web pages. Over the years, its role has significantly expanded, and now it powers both client-side and server-side applications, thanks to environments like Node.js. JavaScript is an interpreted language, which means it’s executed line-by-line in real time, unlike Java’s compiled approach.

2. What are callbacks?

A callback is a function that is passed as an argument to another function and is executed after the completion of that function. Callbacks are foundational in JavaScript, especially for asynchronous operations like reading files or making API calls, because they allow functions to run in the background and call the callback once they’re done. This mechanism ensures that certain operations are completed before proceeding, thereby managing the flow of asynchronous tasks within the language.

3. Why is JavaScript single-threaded?

JavaScript is a single-threaded language, which means only one line of code can be executed at one time. This is primarily because of JavaScript’s origins and the nature of its main application: web browsers. When Netscape first created JavaScript in the 1990s, its main purpose was to add interactivity to web pages.

4. What is the use of void (0)?

In JavaScript, void(0) is an expression that returns the undefined value. Historically, it was commonly used in hyperlink href attributes to prevent the browser from navigating to a new page when a user clicked the link. By setting href=”javascript:void(0);”, developers could ensure that the hyperlink, when activated, would execute JavaScript without triggering a page refresh or navigation.

5. What is the difference between == and === in JavaScript?

Double Equals (==): This is the loose equality operator. It compares two values for equality after performing any necessary type of coercion. This means that if the compared values are of different types, JavaScript will try to convert one or both values to a common type before comparing them.

Example: 1 == “1” returns true because the string “1” is implicitly coerced to the number 1 before the comparison.

Triple Equals (===): This is the strict equality operator. It compares two values for equality without performing type coercion. If the values are of different types, the comparison will immediately return false. It’s generally recommended to use === over == in most situations in order to avoid unexpected results due to type coercion.

Example: 1 === “1” returns false because no type of coercion is performed, and a number is not strictly equal to a string.

6. What are truthy and falsy values in JavaScript?

A value is considered “truthy” if it evaluates to true in a Boolean context; a value is “falsy” if it evaluates to false. The following are the primary falsy values in JavaScript:

false

0 and -0

“” (empty string)

null

undefined

NaN

7. Explain the concept of hoisting in JavaScript.

Hoisting in JavaScript is a behavior in which variable and function declarations move to the top of their containing scope during the compilation phase before the code is executed. This means that variables and functions can be used before they are declared in the code.

Tesla Coding Interview Questions and Answers for Python

1. What are the key features of Python?

Python boasts the following features:

Python is free and open-source: Python is available for free on its official website. Being open-source, its source code is accessible to everyone, allowing you to freely download, use, and share it.

Python supports GUI programming: You can create graphical user interfaces using modules like PyQt5, PyQt4, wxPython, or Tk.

It supports object-oriented programming: Python is an object-oriented programming language in which objects are associated with both properties and methods.

It’s simple to learn to write code in Python: Because Python is a high-level programming language that is simpler to learn, coding in Python is straightforward. Even beginners can grasp its basics quickly. This makes Python developer-friendly.

It is a portable language: You can run Python code on any platform, so if something is written on Windows, it can run on other operating systems as well.

Python is an interpreted language: This means that the Python program’s source code is converted into bytecode, which is subsequently executed by the Python virtual machine. This distinguishes Python from other compiled languages like C and C++, where the code undergoes a build and linking process.

2. Explain the difference between lists and tuples in Python.

The main difference between lists and tuples is that tuples are immutable — they can’t be changed. On the other hand, lists are mutable and can be modified. However, lists are less memory-efficient than tuples.

3. What does PEP 8 mean?

PEP 8 stands for Python Enhancement Proposal 8. It presents coding standards for Python programming. These guidelines help in writing clear, skillfully indented code.

4. What is type conversion in Python?

When you change the value of one data type (like integer, string, float) to another in Python, it’s called type conversion. There are two main type conversion methods: Implicit Type Conversion and Explicit Type Conversion.

5. What is Python Path?

Pythonpath is an environment variable that directs the Python interpreter to locate libraries and applications. It functions the same way as the PATH environment variable in languages like C but includes extra directories for Python modules.

6. What are namespaces in Python?

A namespace is like a dictionary of established symbols paired with details about the objects they point to. The object names serve as keys, and the associated objects represent the values.

Tesla Advanced Interview Questions 

1. Explain the concept of closures in JavaScript.

Closures in JavaScript refer to the ability of a function to remember and access variables from an outer (enclosing) scope, even after the outer function has finished executing. Closures are created whenever a function is defined inside another function, with the inner function referencing variables from the outer function. This behavior allows for data encapsulation and private data patterns in JavaScript.

2. What is the prototype chain, and how does prototypal inheritance work in JavaScript?

The prototype chain in JavaScript is a mechanism that allows objects to inherit properties and methods from other objects. Every object in JavaScript has a hidden property called [[Prototype]] — often accessible via the __proto__ property or Object.getPrototypeOf() — which points to another object, the “prototype.”

Prototypal Inheritance:

In JavaScript, inheritance is based on prototypes. When one object inherits from another, it essentially sets its prototype to point to the parent object. When a property is not found on the child object, the prototype chain can be traversed to find the property on the parent object (or further up if necessary).

3. Explain the differences between Promises and async/await.

Promises: Introduced in ES6, a Promise represents a future value — either a resolved value or a reason for rejection. Promises have three states: pending, resolved (fulfilled), or rejected. Promises are usually used with .then() for resolved values and .catch() for errors.

async/await: Introduced in ES8 (or ES2017), async/await is syntactic sugar on top of Promises, designed to make asynchronous code look and behave more like synchronous code. An async function always returns a promise, and inside an async function, you can use the await keyword to pause the function’s execution until the promise is resolved, making it easier to read and write asynchronous code.

4. When do you use *args and **kwargs in Python?

When you are unsure about the number of keyword arguments to pass to a function, you can use *args and **kwargs as arguments of a function. It should be noted that *args are always used before **kwargs.

5. What is SVM in Python?

Support Vector Machines (SVMs) are supervised learning algorithms used for classification, regression, and detecting outliers. One of their main benefits is their efficiency in handling high-dimensional spaces.

6. Why do you use self in Python?

‘Self’ refers to the instance of the class in Python. Through ‘self,’ we can access the class’s attributes and methods. It associates the attributes with the provided arguments. The need for using ‘self’ arises because Python doesn’t employ the ‘@’ notation for referencing instance attributes.

7. What are Python docstrings?

A docstring is a text description embedded within a Python module, class, function, or method. This way, programmers can understand what the module does without seeing the details of the code itself. Often, these docstrings are used to automatically create online documentation.

8. Why does Python use __ init __?

In Python, the __init__ method is part of a class. Its purpose is to initialize the object’s attributes when you create it. When defining the __init__(self) method, ‘self’ is included as a default parameter in the argument list. This ‘self’ parameter refers to the instance of the class itself. It’s not important to always include an __init__ function, but if you don’t, Python will provide a default constructor for the class.
