RunKit + 
Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including @extra-asciinema/retime-data. Try it out:
const asciinema = require("extra-asciinema");
const fs = require("fs");
var d = fs.readFileSync("saved.cast", "utf8");
d = asciinema.retimeData(d, {inputDelay: 2});
fs.writeFileSync("saved.cast", d);
