Video: Loops in JavaScript (Bulgarian)
Video lecture about loops in JavaScript.
The video is recorded in 2014 in a training I was delivering in Telerik Academy.
Loops are programming constructs that execute a block of code multiple times based on a specific condition or set of conditions. In JavaScript, there are several types of loops, including the 'while' loop that executes code as long as a condition is true, and the 'do … while' loop which ensures the code runs at least once before checking the condition. The 'for' loop provides a concise way to iterate through a sequence, specifying initialization, condition, and afterthought (like incrementing). Additionally, there are special operators such as 'break', which immediately exits the loop, and 'continue', which skips the rest of the current iteration and proceeds to the next one. Nested loops occur when a loop is placed inside another loop, allowing for complex iteration patterns.
Topics covered:
- What is a Loop?
- Loops in JavaScript
- while loops
- do … while loops
- for loops
- Special loop operators
- break, continue
- Nested loops
Video: Operators and Expressions in JavaScript (Bulgarian)
Video lecture about operators and expressions in JavaScript.
The video is recorded in 2015 in a training I was delivering in Telerik Academy.
This lecture provides a comprehensive examination of JavaScript operators, encompassing arithmetic, logical, bitwise, comparison, and assignment operators, each with their unique functions in data manipulation and logical flow control. We also touche on operator precedence, explaining how the language interprets multiple operations in an expression. Additionally, we discuss "other operators" like the ternary and typeof operators, culminating with an exploration of expressions in JavaScript—combinations of values and operators that can be evaluated into a single value, contributing to more effective and efficient code.
Topics covered:
- Operators in JavaScript
- Arithmetic Operators
- Logical Operators
- Bitwise Operators
- Comparison Operators
- Assignment Operators
- Other Operators
- Operator Precedence
- Expressions

Dynamic HTML (DHTML) is a combination of web technologies used to create interactive and animated web pages that can respond to user actions without requiring a page reload. To create DHTML, you need to have a good understanding of HTML, XHTML, CSS, JavaScript, and the Document Object Model (DOM). JavaScript is a programming language used to create interactive effects and dynamic content in web pages. It has a simple syntax and can be embedded in HTML pages. Pop-up boxes are a common JavaScript feature used to display messages or alerts to users. Debugging is an essential process in JavaScript development to find and fix errors in the code. Overall, these topics are essential for web developers to create engaging and dynamic web pages using JavaScript and related technologies.
Topics covered:
- Dynamic HTML
- How to Create DHTML?
- XHTML, CSS, JavaScript, DOM
- Intro to JavaScript
- JavaScript in Web Pages
- JavaScript Syntax
- Pop-up boxes
- Debugging in JavaScript
Video: Data Types and Variables in JavaScript (Bulgarian)
Video lecture about data types and variables in JavaScript.
The video is recorded in 2015 in a training I was delivering in Telerik Academy.
JavaScript supports several data types such as integers, floating-point numbers, booleans, and strings. These data types are used to store different kinds of values in a program. To store and manipulate data in JavaScript, variables are used. Variables are declared using the "var" keyword, and values can be assigned to them using the assignment operator. Variables must be given an identifier, which is a unique name that is used to refer to the variable throughout the program. By understanding data types and variables, JavaScript developers can create robust and dynamic programs.
Topics covered:
- Data Types
- Integer
- Floating-Point
- Boolean
- String
- Declaring and Using Variables
- Identifiers
- Declaring Variables and Assigning Values
