In terms of the topics discussed during the interview, we touched upon various subjects such as: TypeScript vs. JavaScript: We discussed the advantages and disadvantages of TypeScript compared to JavaScript. TypeScript offers static typing, better tooling, and improved error checking, but it requires compilation and has a steeper learning curve compared to JavaScript. Closures: The interviewer asked about closures in JavaScript, which are functions that retain access to variables from their outer scope. We discussed how closures can help with encapsulation and creating private variables. jQuery: The interviewer inquired about my experience with jQuery, a JavaScript library that simplifies HTML traversal, event handling, and animation. I shared my knowledge of jQuery's features and how it can facilitate web development. Scopes: We talked about the different scopes in JavaScript, including global, function, and block scopes. I explained how variables have different accessibility and lifetimes depending on their scope. aria-roles: The interviewer asked about ARIA roles, which are attributes used to enhance accessibility in HTML elements for assistive technologies. I described how they define the roles and properties of elements. var, let, const: We discussed the differences between var, let, and const in JavaScript. I explained that var is function-scoped, while let and const are block-scoped. Additionally, let allows reassignment, while const declares a constant variable. !important: The interviewer asked about the CSS "!important" declaration. I explained that it gives priority to a specific style rule over others, allowing for overriding conflicting styles. Differences between TypeScript and JavaScript: We compared TypeScript and JavaScript, discussing how TypeScript is a typed superset of JavaScript. TypeScript provides static typing, better tooling, and enhanced error checking, making it suitable for larger projects. Why TypeScript: The interviewer asked why TypeScript is preferred over JavaScript in certain scenarios. I highlighted TypeScript's benefits such as static typing, improved code maintainability, and better collaboration within teams. Hoisting: The topic of hoisting in JavaScript came up, which refers to the behavior where variable and function declarations are moved to the top of their scope during compilation. I explained that only variable declarations are hoisted, not their assignments. HTTP Status Code Groups: We briefly discussed HTTP status code groups, which categorize different types of responses. I mentioned common groups like 2xx for successful responses, 4xx for client errors, and 5xx for server errors. XSS: The interviewer asked about cross-site scripting (XSS) and its impact on web security. I provided an overview of XSS, which involves injecting malicious scripts into web pages, and explained the importance of preventing XSS vulnerabilities.
