Pressing left mousebutton

I am looking to make a javascript code that can be put in the google console. This code should press the left button at a really high speed. I tried with a code like this:

var event = new KeyboardEvent('keydown', {
    key: 'g',
    ctrlKey: true
});

setInterval(function(){
    for (i = 0; i < 100; i++) {
        document.dispatchEvent(event);
    }
}, 0);

This code only presses G. Now my problem is what defination makes it press the left mouse button.
What should I replace G with to make it press the left mouse button? This code will be used to “cheat” in capybara clicker!

Thanks, Ivar!

I tried this code, and it didnt work. I want this code to instead of pressing g at a fast rate, it should press the left mouse button!

var event = new KeyboardEvent('keydown', {
    key: 'g',
    ctrlKey: true
});

setInterval(function(){
    for (i = 0; i < 100; i++) {
        document.dispatchEvent(event);
    }
}, 0);

You want a mouse event.

let event = new MouseEvent('click', {
    button: 0, // Left button is represented by 0
    bubbles: true,
    cancelable: true
});
const element = document.querySelector('what you want to click');
setInterval(function(){
  for (i = 0; i < 100; i++) {
    element.dispatchEvent(event);
  }
}, 0); //  execute "immediately", or more accurately, the next event cycle.

You MAY want to change the 0 to something else since the game might have a debounce on the click

I tested this code on google’s homepage – it clicks many times (but of course only one click is needed here)

let event = new MouseEvent('click', {
    button: 0, // Left button is represented by 0
    bubbles: true,
    cancelable: true
});
const btn = document.querySelector('[aria-label="I\'m Feeling Lucky"]')
setInterval(function(){
  for (i = 0; i < 10; i++) {
    btn.dispatchEvent(event);
  }
}, 0);
