TypeScript : Keep Month and Year to date

I have one date, I would like to take month and year to this date in Typescript.

For example:

If I have lun. 1 juil. 2024, my code must be return juil 2024.

Can you help me please?

You can use a map for the months, then use Date() and toLocaleDateString():

const months: { [key: string]: string } = {
  "juil.": "Jul", // map your month like this
};

function getDate(dt: string): string {
  const D = dt.split(" ");
  const day = D[1];
  const month = months[D[2]];
  const year = D[3];
  const date = new Date(`${month} ${day} ${year}`);
  const options: Intl.DateTimeFormatOptions = {
    month: "short",
    year: "numeric",
  };
  const dfr = date.toLocaleDateString("fr-FR", options);
  const [m, y] = dfr.split(" ");
  return `${m.replace(".", "")} ${y}`;
}

console.log(getDate("lun. 1 juil. 2024"));

Prints

juil 2024

Or you can use a pattern to match it:

function matchDate(dt: string): string {
  const match = dt.match(/(\w+)\.?\s+(\d{4})/);
  return match ? `${match[1]} ${match[2]}` : "";
}

console.log(matchDate("lun. 1 juil. 2024"));

Pritns

juil 2024
