JavaScript Animate Counter (Number Roll-Up)
Smoothly animates a number from a start value to an end value over a given duration using requestAnimationFrame. Supports a custom easing function (defaults to ease-out quad). Ideal for dashboard stat widgets, donation counters, and any UI where a bare static number would be less impactful.

JavaScript Generate Initials Avatar (Canvas)
Draws a coloured circular avatar with up to two initials on an HTML5 Canvas and returns it as a data URL. Generates a consistent background colour from the name string so the same user always gets the same colour. Useful as a fallback when a user has no profile photo.

JavaScript Keyboard Shortcut Manager
Registers global keyboard shortcuts with a simple key-combo syntax ("ctrl+k", "meta+shift+p"). Handles modifier keys (ctrl, alt, shift, meta) and prevents default browser behaviour when a shortcut matches. Shortcuts can be unregistered individually or all at once, making it easy to scope shortcuts to page sections or modals.
