Coursera 上的 JavaScript 认证考试 JSE-40-01 备考课程（2025 版）是一门旨在帮助学员为 JavaScript 研究所的 JSE-40-01 认证考试做好准备的课程。 该课程包含六套练习测试，涵盖了 JSE-40-01 考试的所有知识领域。每道题目都附有详细的解释以及可供学员运行和加深理解的“Try-It-Yourself-Code”。学员还可以下载所有练习题的代码。 课程大纲主要包括以下几个部分： * **JavaScript 导论与计算机编程基础：** 学习解释器、编译器、客户端与服务器端编程等基本概念，了解如何设置和使用编程环境，并能编写第一个客户端 JavaScript 程序。 * **变量、数据类型与类型转换：** 掌握变量的命名、声明、初始化和修改，理解作用域、代码块、遮蔽和提升等概念，熟悉布尔值、数字、BigInt、undefined、null 等基本数据类型，学习字符串的特性（包括字符串字面量、转义符、字符串插值、基本属性和方法），并能实际运用数组（Array）和对象（Object）等复杂数据类型。 * **运算符与用户交互：** 学习运算符的分类和使用，熟练掌握赋值、算术、逻辑和比较运算符，理解条件运算符、typeof、instanceof 和 delete 运算符，了解运算符的优先级和结合性，并能使用 alert、confirm 和 prompt 对话框实现基础的用户交互。 * **控制流 - 条件执行与循环：** 学习使用 if-else 和 switch 语句进行条件执行，掌握 for、while 和 do-while 循环，理解并运用 break 和 continue 语句，以及 for-in 和 for-of 语句来遍历对象属性和数组元素。 * **函数：** 能够声明和调用函数，理解参数传递和返回值，掌握局部变量和变量遮蔽，理解函数作为一等公民的概念，学习函数表达和将函数作为参数传递，初步理解递归，熟悉回调函数及其在 setTimeout 和 setInterval 中的异步应用，并掌握箭头函数的写法。 * **错误、异常、调试与排错：** 理解语法错误、语义错误和逻辑错误的区别，了解异常的概念，区分 JavaScript 中常见的错误类型（SyntaxError, ReferenceError, TypeError, RangeError），学习使用 try-catch-finally 处理异常，掌握 throw 语句用于抛出自定义异常，并学会使用调试器进行代码分析（如单步执行、查看和修改变量、测量代码执行时间）。 本课程旨在全面提升学员的 JavaScript 编程能力，使其能自信地应对 JSE-40-01 认证考试。
Now is the time to get certified for JavaScript! JavaScript Institute JSE-40-01: Certified Entry-Level JavaScript Programmer There are six practice tests with preparation questions from all knowledge areasto prepare for the JSE-40-01 exam at the JavaScript Institute.Every question has an explanation and a Try-It-Yourself-Codewhich you can run to better understand the topic.You can download the Try-It-Yourself-Code for all questions.(The download link will be in your welcome message.)Exam SyllabusIntroduction to JavaScript and Computer Programmingunderstand the fundamental programming concepts, such as: interpreting and the interpreter, compilation and the compiler, client-side vs. server-side programming;have a basic knowledge of how to set up and use a basic programming environment (online or local)gain skills allowing them to run their first JavaScript program on the client side (both as an element embedded in the HTML page and directly in the browser console).Variables, Data Types, and Type Castinghave the knowledge and skills to work with variables, i.e. naming, declaring, initializing and modifying their values;understand concepts such as scope, code blocks, shadowing, hoisting;know the basic properties of primitive data types such as boolean, number, bigint, undefined, null, and be able to use them;be familiar with the basic properties of the primitive data type string, including string literals - single or double quotes, escape character, string interpolation, basic properties and methods;know the basic properties of complex data types such as Array and Object (treated as a record) and be able to use them in practice.Operators and User Interactionknow what operators are and how we classify them (by type of operands, by number of operands, etc.)be able to use assignment, arithmetic, logical, and comparison operators in practice;have an understanding of the operation of the conditional operator and the typeof, instanceof, and delete operators;understand what the precedence and associativity of basic operators are and be able to influence it by means of bracket grouping;be able to perform basic two-way communication with the program user using the alert, confirm, and prompt dialog boxes.Control Flow - Conditional Execution and Loopsbe able to force conditional execution of a group of statements (make decisions and branch the flow) using if-else and switch commands;be able to force a group of statements to repeat in a loop using the for, while, and do-while commands, using both dependent and independent conditions on the number of iterations;understand and be able to use loop-specific break and continue instructions;be able to use the for-in statement to iterate over properties of an object;be able to use the for-of statement to walk through the elements of an array.Functionsbe able to declare and call functions;know how to pass call arguments to a function and return the result of its operation from it;understand the concept of a local variable and the effect of shadowing variables with the same names within a function;know that a function in JS is a first-class member and be able to take advantage of this by declaring functions using function expression and passing functions as arguments to calls of other functions;understand the concept of recursion in the context of functions and be able to solve simple programming problems by using it;have a basic understanding of the callback function and be able to use it asynchronously in conjunction with the setTimeout and setInterval methods;have a clear understanding of arrow function notation and be able to write functions alternatively as a regular declaration, a function expression, and an arrow function.Errors, exceptions, debugging, and troubleshootingunderstand the differences between syntactic, semantic, and logical errors;understand the concept of an exception and distinguish between the basic exceptions generated by JS when an error occurs: SyntaxError, ReferenceError, TypeError, RangeError;have the ability to handle exceptions using the try-catch-finally statement;be able to generate their own exceptions using the throw statement;have the skills to use the debugger for basic analysis of their own code, including: step-by-step execution, viewing and modifying variables, and measuring code execution time.
