Why is the textContent on both sides of the variable?

36,427 PointsI hope I am understanding your question correctly. Did you mean: "Why is the textContent on both sides of the equals sign?"? After watching the video, I believe you are referencing this line of code:
listItems[i].textContent = listItems[i].textContent.toUpperCase()
This function:
listItems[i].textContent.toUpperCase()
Only RETURNS the uppercase value of whatever listItems[i].textContent happens to be on that iteration. This alone:
listItems[i].textContent.toUpperCase()
does not change listItems[i].textContent itself. The only way to achieve a persisting modification of the listItems[i].textContent text is to reassign the modified textContent back to itself, which is what this line of code it doing:
listItems[i].textContent = listItems[i].textContent.toUpperCase()
Is that what you meant? Anyway, I hope that helps. Happy coding!
