Why will my code only execute the first time I click?

I'm curious as to why this code runs the first time I click in the header area of the page but subsequent clicks do absolutely nothing.

Code:

const head = document.getElementById("myHeading");

head.addEventListener('click', () => {

if (head.style.color = "black") {

  head.style.color = "green";

} else if (head.style.color = "green") {

  head.style.color = "red"; 

} else if (head.style.color = "red") {

  head.style.color = "black";

}

});

I see two issues:

  • you have assignments ("=") instead of comparisons ("==") in your "if" statements
  • unless you set it using inline style, the initial value of the "color" property is not "black" (it's just empty)

Thank you so much! I am just learning the basics of JS, having come from VBA, and "=" vs "==" keeps slipping my mind.
