Uploaded by

Vinoth M

The document contains 10 coding programs written in HTML and JavaScript that demonstrate different programming concepts: 1. The first program calculates and displays squares, square roots, cubes, and complements of numbers from 1 to 100. 2. The second program creates a basic calculator that can perform addition, subtraction, multiplication, and division operations. 3. The third program sorts an array of string elements in alphabetical order. 4. The remaining programs demonstrate additional concepts like hit counters, form validation, digital clocks, mouse events, frames, and a basic search engine.
