Explore hoisting by predicting what gets logged when a function runs and when a text variable is logged, sharpening your JavaScript interview problem-solving skills.
Explore how scope in JavaScript governs variable visibility, differentiating global and local variables, and how functions create new scopes, leading to reference errors or global assignments.
Examine the given code to determine what will be logged when the program is read, focusing on the behavior of const, var, and let.
Explore how var, let, and const differ in scope and reassignment, with block scope versus global scope illustrated and ES6 introducing these keywords.
Analyze how the this keyword affects what gets logged to the console in the shown code. Determine the outputs for the full name at lines 12 and 16.
Identify use cases for arrow functions and explain at least one limitation, equipping you to tackle interview questions on JavaScript syntax.
Explore a use case for arrow functions and name a limitation, such as their lack of this binding in object methods and their inability to be used as constructors.
The Cracking the JavaScript Coding Interview course provides a variety of practice problems comprised of different topics and solutions related to JavaScript and general programming concepts. Students will be able to solve problems from a wide range of JavaScript coding questions. Anyone looking to prepare for front-end, JavaScript related interviews, and general coding interviews will benefit greatly from this course. Students will learn what kinds of programming interviews are like and be exposed to commonly asked JavaScript questions. They will also be able to master the relevant skills concepts and techniques necessary to excel in their upcoming coding interviews.
Students will be able to understand both the fundamental and advanced concepts in JavaScript. Some of the most popularly asked JavaScript concepts that this course covers are hoisting, scopes, the ‘this’ keyword, browser methods, the event loop, callbacks, promises, async await, closures, currying, JavaScript events and some commonly used Array methods in Javascript such as bind, filter, map, call and apply. This course also covers more general programming concepts like recursion, objects, operators and array manipulation. This course is best for students who have some beginners knowledge or intermediate in JavaScript or programming, but do not need to have an advanced level of knowledge in JavaScript.
