Panel 1: Bilbo Baggins ponders, “After all… why should I care about the difference between int and String?
Panel 2: Bilbo Baggins is revealed to be an API developer. He continues, “JSON is always String, anyways…”
Unless you’re dealing with some insanely flexible schema, you should be able to know what kind of number (int, double, and so on) a field should contain when deserializing a number field in JSON. Using a string does not provide any benefits here unless there’s some big in your deserialzation process.
What’s the point of your schema if the receiving end is JavaScript, for example? You can convert a string to BigNumber, but you’ll get wrong data if you’re sending a number.
What makes you think so?
const bigJSON = '{"gross_gdp": 12345678901234567890}'; JSON.parse(bigJSON, (key, value, context) => { if (key === "gross_gdp") { // Ignore the value because it has already lost precision return BigInt(context.source); } return value; }); > {gross_gdp: 12345678901234567890n}https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse
