Describe the bug

• I want to render a page with a big list of some goods with some dates, e.g. expiration
• I have code similar to

const now = dayjs();
const list = [];
for (const item of goods) {
    list.push({
        item,
        expires: now.add(item.daysLeft).format(`D MMMM YYYY`)
    });
}
// render the list

This takes too long, because every call to .format() does much of work under the hood:

The worst things performance-wise:

• the local functions getShort, get$H, meridiemFunc, matches are created on every call, even if not needed
• the same format string D MMMM YYYY is processed via str.replace(C.REGEX_FORMAT, ...) again and again on every call

Expected behavior
I'd like to have a way to preprocess/precompile format string in such a way that the following calls to format() will be very fast. E.g.

const now = dayjs();
const list = [];
const precompiledFormat = dayjs.precompileFormat(`D MMMM YYYY`);
for (const item of goods) {
    list.push({
        item,
        expires: now.add(item.daysLeft).format(precompiledFormat),
        // or maybe:
        expires: precompiledFormat(now.add(item.daysLeft))
    });
}
// render the list
