This interactive word search puzzle displays 15 programming-related terms hidden in a 15×15 grid of letters. Users click and drag to select letters horizontally, vertically, or diagonally, and matching words become highlighted in the grid and crossed off in the word list. The implementation uses plain JavaScript DOM manipulation with `addEventListener` for mouse events, random placement with collision detection for word positioning, and CSS Grid for rendering the interactive letter cells. The "New Game" button regenerates the puzzle with fresh random placements.
