[Typescript] @overload for JSDoc
TypeScript 5.0 now allows JSDoc to declare overloads with a new @overload
tag. Each JSDoc comment with an @overload
tag is treated as a distinct overload for the following function declaration.
// @ts-check
/**
* @overload
* @param {string} value
* @return {void}
*/
/**
* @overload
* @param {number} value
* @param {number} [maximumFractionDigits]
* @return {void}
*/
/**
* @param {string | number} value
* @param {number} [maximumFractionDigits]
*/
function printValue(value, maximumFractionDigits) {
if (typeof value === "number") {
const formatter = Intl.NumberFormat("en-US", {
maximumFractionDigits,
});
value = formatter.format(value);
}
console.log(value);
}
