1 line of code: How to shuffle an array

const shuffle = arr => [...arr].sort(() => 0.5 - Math.random());
Enter fullscreen mode Exit fullscreen mode

Returns a new array with shuffled items.

Be aware, that the shuffled items are not truly random because Math.random will return a pseudo-random number.


The repository & npm package

You can find the all the utility functions from this series at github.com/martinkr/onelinecode
The library is also published to npm as @onelinecode for your convenience.

The code and the npm package will be updated every time I publish a new article.
