+### RGB to hexadecimal
+
+Convert each value to a hexadecimal string, using `toString(16)`, then `padStart(2,'0')` to get a 2-digit hexadecimal value.
+Combine values using `join('')`.
+
+```js
+var rgbToHex = (r, g, b) =>
+  [r,g,b].map( v => v.toString(16).padStart(2,'0')).join('');
+```
+
+### URL parameters
+
+Use `match()` with an appropriate regular expression to get all key-value pairs, `map()` them appropriately.
+Combine all key-value pairs into a single object using `Object.assign()` and the spread operator (`...`).
+Pass `location.search` as the argument to apply to the current `url`.
+
+```js
+var getUrlParameters = url =>
+  Object.assign(...url.match(/([^?=&]+)(=([^&]*))?/g).map(m => {[f,v] = m.split('='); return {[f]:v}}));
+```
+
+### UUID generator
+
+Use `crypto` API to generate a UUID, compliant with [RFC4122](https://www.ietf.org/rfc/rfc4122.txt) version 4.
+
+```js
+var uuid = _ =>
+  ( [1e7]+-1e3+-4e3+-8e3+-1e11 ).replace( /[018]/g, c =>
+    (c ^ crypto.getRandomValues(new Uint8Array(1))[0] & 15 >> c / 4).toString(16)
+  )
+```

 ### Validate number
 
 Use `!isNaN` in combination with `parseFloat()` to check if the argument is a number.
