Function isInteger not found

I ran into an issue where I cannot access a method of Number called isInteger..

if (!(Number.isInteger(schedule[letter][day][event]["Duration"]))) throw "Validation failed";

Running the following code returns Uncaught Error: Function "isInteger" not found!::

console.log(Number.isInteger(1));

How can I install the Number class into my Bangle.js? Is there any way to fix this?

I'm afraid Number.isInteger isn't in Espruino, but you can fake it with this I believe:

Number.isInteger = it => isFinite(it) && Math.floor(it) === it;
