I'm confused about the distinction between using querySelector() and getElementById(). From what I understand, querySelector is able to retrieve an element using any selector, giving it more flexibility.
Are there additional contrasts between the two methods? In what scenarios would it be more appropriate to use getElementById instead of querySelector?
Based on the findings outlined in the referenced article:
It was discovered that getElementById() can perform approximately 15 million operations per second, while querySelector() only manages around 7 million operations per second in Chrome's latest version.
If achieving such high performance levels is a priority for you, then prioritizing this approach would be advisable. Otherwise, there is no significant distinction between the two methods aside from the previously mentioned flexibility.
