Learn JavaScript Basics

Learn how JavaScript runs in the browser to execute programs, handle events like clicks, and update the DOM to reflect user actions and form validation.

Learn how to write internal javascript, embed it in html with script tags, and see how the browser runs javascript before rendering the dom.

Learn how to write single-line and multi-line comments in JavaScript, using examples that show how comments prevent code execution and help document code with alerts and basic demonstrations.

Create an external JavaScript file, place it in a separate folder, and embed it in your HTML using a script tag with the src attribute.

Learn inline JavaScript by embedding code inside HTML tags and handling events like onclick to trigger alerts, and compare inline, internal, and external approaches.

Explore primitive data types in JavaScript, including numbers, strings, and booleans. Learn decimals, string quotes, and concatenation with the plus operator, and view results in the browser console.

Explore string operations in JavaScript by using the plus operator to concatenate strings, and apply methods like index, substring, lowercase, and uppercase with user inputs.

Learn how to create and manipulate arrays in JavaScript, including defining arrays with square brackets, accessing elements by zero-based indices, updating values, and appending new items.

understand how if statements check a condition and trigger actions based on true or false. learn to use else if, nested conditions, and boolean expressions with braces and else blocks.

Explore while loops and do-while loops in JavaScript, control iterations with a counter and conditions, print the counter, avoid infinite loops, and practice with hands-on exercises.

Learn how to write a for loop with initialization, a condition, and an increment operation, and understand the execution flow through examples that print counts from zero to ten.

Write and call JavaScript functions using the function keyword, parameters, and return values. Explore named and anonymous functions with examples like alerts and basic arithmetic.

Explore how events work in JavaScript basics, using on click and on mouse over attributes to trigger alerts and call functions from event handlers on page elements.

Access the element by its id, read the text input's value from the DOM, and alert or log the captured value to demonstrate reading a text box.

Learn how to access and validate form elements in JavaScript by creating a simple name and email form. Use getElementById or getElementsByTagName to read values and perform validation.

Develop a JavaScript guessing game by prompting users to guess a number from 1 to 10, using a loop and conditional logic to reveal results.
