I found myself in the situation where I wanted to convert a BigInt value to a Number value. Knowing that my value is a safe integer, how can I convert it?

Turns out it's as easy as passing it to the Number constructor:

const myBigInt = BigInt(10);  // `10n` also works

const myNumber = Number(myBigInt);

Of course, you should bear in mind that your BigInt value must be within [Number.MIN_SAFE_INTEGER, Number.MAX_SAFE_INTEGER] for the conversion to work properly, as stated in the question.
