Javascript – How can I code a cooldown to a key press?

In my game, there is a "boost" option that pushs the player forward when they press Left Shift.
The problem is you can spam the button and go flying across the map.
To resolve this issue I want to add a small cooldown that will give the player good speed, but also won’t let the player exploit the feature by speeding across the entire map in 5 seconds.

I have tried looking up how to fix the issue but nothing helped because the code was in something like c++ or python.

Here is the code for my movement:

function Input() {
    document.addEventListener('keydown', (event) => {
    var name = event.key;
    var code = event.code;
    if (code == "ArrowRight" || code == "KeyD") {
        velX+= 5
    }
    if (code == "ArrowDown" || code == "KeyS") {
        velY+= 5
    }
    if (code == "ArrowUp" || code == "KeyW") {
        velY-= 5
    }
    if (code == "ArrowLeft" || code == "KeyA") {
        velX-= 5
        
    }
    if (code == "ShiftLeft") {
        velX *= 2
        velY *= 2
    }
    

    }, false);
}

    You can add a set timeout for your boost along with a boolean flag and make sure the user has some interval within each boost.

    // Define variables to track boost state and cooldown
let isBoosting = false;
let boostCooldown = false;

// Function to handle boost
function boost() {
  if (!isBoosting && !boostCooldown) {
    // Start boosting
    isBoosting = true;
    console.log("Boosting!");

    // Set a timer for the boost duration (e.g., 3 seconds)
    setTimeout(() => {
      // Stop boosting after the boost duration
      isBoosting = false;
      console.log("Boost ended!");

      // Set a cooldown timer (e.g., 5 seconds)
      boostCooldown = true;
      setTimeout(() => {
        // Reset the cooldown after the cooldown duration
        boostCooldown = false;
        console.log("Boost cooldown ended!");
      }, 5000); // Cooldown duration in milliseconds
    }, 3000); // Boost duration in milliseconds
  }
}

// Example: Call the boost function when the Left Shift key is pressed
document.addEventListener("keydown", function (event) {
  if (event.key === "Shift") {
    boost();
  }
});

    just add a variable named Pressed (or something dosent matter) set it to false and when the user uses that boost set it to true
    and let a setTimeout with the cooldown u want that boost to be run in bg
    when the time reaches 0 set Preseed to false
    also make sure to check if the Pressed is false before running the boost code
