Unable to understand useCapture parameter in addEventListener

Events can be activated at two occasions: At the beginning (“capture”), and at the end (“bubble”).

Events are executed in the order of how they’re defined. Say, you define 4 event listeners:

window.addEventListener("click", function(){console.log(1)}, false);
window.addEventListener("click", function(){console.log(2)}, true);
window.addEventListener("click", function(){console.log(3)}, false);
window.addEventListener("click", function(){console.log(4)}, true);

The log messages will appear in this order:

• 2 (defined first, using capture=true)
• 4 (defined second using capture=true)
• 1 (first defined event with capture=false)
• 3 (second defined event with capture=false)
