This question already has an answer here:
I was looking for solutions for measuring string height of a HTML5 canvas element. I found this solution but that doesn't satisfied my needs. Later, when I came up with my own solution, I come back and made my own answer. But then while looking at other answers more attentively I found that one answer uses the same approach as mine.
Should I delete my answer or not? Should I add answers with the same approach but different content?
