The JSE - Entry-Level JavaScript Programmer (JSE-40-01) mock exam is designed to help individuals prepare for the official JSE certification. This exam evaluates foundational knowledge of JavaScript programming, including basic syntax, variables, data structures, and common programming concepts. The mock exam includes 30 questions in both single-selection and multiple-selection formats, testing candidates on their ability to apply JavaScript in practical scenarios.The exam duration is 45 minutes, with 5 minutes allocated for a tutorial and NDA. To pass, candidates must achieve a score of at least 70%. This mock exam serves as an excellent practice tool for those aiming to achieve the JSE certification, which is the first step toward becoming a certified JavaScript programmer.Exam Pattern- Number of Questions: 30- Passing score: 70%- Duration: 40 Minutes- Questions Type: Multiple ChoiceJSE - Certified Entry-Level JavaScript Programmer Exam Syllabus1. Introduction to JavaScript and Programming BasicsKey Learning Outcomes:Understand core programming concepts such as interpretation vs. compilation, client-side vs. server-side programming.Gain knowledge on setting up a basic programming environment (either online or local).Develop the ability to run the first JavaScript program on the client side, both embedded within an HTML page and directly in the browser console.2. Working with Variables, Data Types, and Type CastingKey Learning Outcomes:Learn to work with variables: naming, declaring, initializing, and modifying their values.Understand scope, code blocks, variable shadowing, and hoisting in JavaScript.Work with primitive data types like boolean, number, bigint, undefined, and null, and their basic operations.Explore string data type properties, string literals (single and double quotes), escape characters, string interpolation, and string methods.Get familiar with complex data types such as Arrays and Objects, and use them in practical applications.3. Using Operators and Interacting with the UserKey Learning Outcomes:Understand the classification of operators based on the type and number of operands.Practice using assignment, arithmetic, logical, and comparison operators.Learn about the conditional operator and other key operators like typeof, instanceof, and delete.Understand operator precedence and associativity, and learn how to modify them with parentheses.Implement basic user interaction using the alert, confirm, and prompt dialog boxes.4. Control Flow: Conditional Statements and LoopsKey Learning Outcomes:Use conditional statements (if-else and switch) to control the flow of execution.Implement loops (for, while, do-while) with varying conditions to repeat statements.Understand and apply the break and continue statements for controlling loop execution.Iterate over object properties using the for-in loop and over array elements using the for-of loop.5. Functions: Declaring, Calling, and Utilizing FunctionsKey Learning Outcomes:Understand how to declare and invoke functions in JavaScript.Learn to pass arguments to functions and return results from them.Understand the concept of local variables and variable shadowing within a function.Treat functions as first-class members of JavaScript: declare functions using function expressions and pass them as arguments to other functions.Explore recursion and use it to solve simple programming problems.Work with callback functions, especially with setTimeout and setInterval.Understand and write functions using regular declarations, function expressions, and arrow function syntax.6. Debugging, Error Handling, and TroubleshootingKey Learning Outcomes:Identify and differentiate between syntactic, semantic, and logical errors in code.Understand the nature of exceptions in JavaScript, including SyntaxError, ReferenceError, TypeError, and RangeError.Learn how to handle exceptions with try-catch-finally statements.Use the throw statement to generate custom exceptions.Utilize the JavaScript debugger for code analysis, including step-by-step execution, viewing and modifying variables, and measuring performance.
