[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);
}
