7,974 PointsCan someone convert this Arrow function to a ES5 style function?
can somebody rewrite this Arrow Function as a ES5 style function? I'm having trouble following how it works and think would help me understand. I've watched the workshop on Arrow Functions but none of the examples really look like the one here.
const myHeading = document.getElementById('myHeading');
const myButton = document.getElementById('myButton');
const myTextInput = document.getElementById('myTextInput');
const resetButton = document.getElementById('resetButton');
myButton.addEventListener('click', () => {
myHeading.style.color = myTextInput.value ;
});
thanks

In the case of an anonymous lambda function like this one, just put the keyword "function" in front of the parentheses, and remove the "arrow":
myButton.addEventListener('click', function () {
myHeading.style.color = myTextInput.value ;
});
