exam process
Introduction to JavaScript and computer programming
understand basic programming concepts such as: interpretation and interpreter, compilation and compiler, client side versus server side programming;
have basic knowledge of setting up and using a simple programming environment (online or local).
gain the skills to run their first client-side JavaScript program (both as an embedded element in an HTML page or directly in the browser console).
Variables, data types, and type conversions
have the knowledge and skills to work with variables, i.e. naming, declaring, initializing, and changing their values;
Understand concepts such as coverage, code blocks, shading, lifting;
know and be able to use the main properties of primitive data types such as boolean, number, bigint, undefined, null;
Get to know the basic properties of the String primitive data type, including string literals – single or double quotes, escape characters, string interpolation, basic properties and methods;
to know the basic properties of complex data types such as arrays and objects (treated as data sets) and to be able to apply them in practice.
Operator and user interaction
know what operators are and how we classify them (by operand type, by number of operands, etc.)
be able to use assignment operators, arithmetic operators, logical operators and comparison operators in practice;
understand how the conditional operator and the typeof, instanceof, and delete operators work;
understand precedents and associative primitive operators and can influence them by grouping in brackets;
can perform basic two-way communication with program users using alert, confirmation, and prompt dialogs.
Control Flow – Conditional execution and loops
can force conditional execution of a group of statements (make decisions and branch flows) with if-else and switch statements;
can force a group of statements to repeat in a loop using for, while and do-while statements, using dependent and independent loop count conditions;
understand and use loop-specific interrupt commands and continue;
can use the for-in operator to iterate over object properties;
to be able to use the for-of statement to iterate over the elements of the array.
function
can declare and execute functions;
know how to pass arguments to function calls and return your work from them;
understand the concept of local variables and the shadowing effect of similarly named variables in a function;
You know that functions in JS are members of first class, and you can exploit them by declaring functions, using function expressions, and passing functions as arguments to call other functions;
understand the concept of recursion in the context of functions and be able to use it to solve simple programming problems;
have basic knowledge of callback functions and be able to use them asynchronously with setTimeout and setInterval methods;
have a clear understanding of arrow function notation and can alternatively write functions as simple declarations, function expressions, and arrow functions.
Errors, exceptions, debugging and troubleshooting
understand the difference between syntactic, semantic, and logical errors;
Understand the concept of exceptions and distinguish between the main exceptions generated by JS when an error occurs: SyntaxError, ReferenceError, TypeError, RangeError;
have the ability to handle exceptions with try-catch-finally statements;
can generate their own exceptions with a throw statement;
Have the skills to use the debugger for basic analysis of their own code, including: tracing, viewing and changing variables, and measuring code execution time.
