How to convert Map key values into array in JavaScript

Question

I have a Map that contains keys and their value. I want to convert all keyvalues into an array

const gameEvents = new Map([
  [17, '⚽ GOAL'],
  [36, '🔁 Substitution'],
  [47, '⚽ GOAL'],
  [61, '🔁 Substitution'],
  [64, '🔶 Yellow card'],
  [69, '🔴 Red card'],
  [70, '🔁 Substitution'],
  [72, '🔁 Substitution'],
  [76, '⚽ GOAL'],
  [80, '⚽ GOAL'],
  [92, '🔶 Yellow card'],
]);

I want that my new array should look like this

['⚽ GOAL','🔁 Substitution','⚽ GOAL' ,'🔁 Substitution', '🔶 Yellow card', '🔴 Red card', '🔁 Substitution','🔁 Substitution',, '⚽ GOAL', '⚽ GOAL', '🔶 Yellow card']

this will do

const gameEvents = new Map([
  [17, '⚽ GOAL'],
  [36, '🔁 Substitution'],
  [47, '⚽ GOAL'],
  [61, '🔁 Substitution'],
  [64, '🔶 Yellow card'],
  [69, '🔴 Red card'],
  [70, '🔁 Substitution'],
  [72, '🔁 Substitution'],
  [76, '⚽ GOAL'],
  [80, '⚽ GOAL'],
  [92, '🔶 Yellow card'],
]);

console.log([...gameEvents.values()]);

Try this:

const gameEvents = [
  [17, '⚽ GOAL'],
  [36, '🔁 Substitution'],
  [47, '⚽ GOAL'],
  [61, '🔁 Substitution'],
  [64, '🔶 Yellow card'],
  [69, '🔴 Red card'],
  [70, '🔁 Substitution'],
  [72, '🔁 Substitution'],
  [76, '⚽ GOAL'],
  [80, '⚽ GOAL'],
  [92, '🔶 Yellow card'],
];

console.log(gameEvents.map(x => x[1]))
