TIL: Random Id
2020-06-09
TIL Number.toString() in javascript takes a radix, which is a handy way to make an short alphanumeric random id.
Occasionally I need to generate an id and end up doing something like:
1 | Math.floor(Math.random() * 1000000000) |
which just feels a little hackish, but generating a full UUID seems like overkill. But this generates a short random alphanumeric string:
1 | Math.random().toString(36).substr(2) |
Which gives you something like “d6gykt0qjmu” a decent simple random id, and feels alot more elegant.
