Why ID is preferred Locator than xpath?

Why is ID Locator preferred over XPath in Selenium? Because id is the unique identifier for the element and it does not change. This makes 'Ids' a very explicit and reliable way to locate elements on the page. Also, all browsers also have highly efficient methods to get an object on the page using their ids.

Which is faster Xpath or ID?

Technically speaking, By.ID() is the faster technique because at its root, the call goes down to document. getElementById(), which is optimized by most browsers. But, finding elements using XPath is better for locating elements having complex selectors, and is no doubt the most flexible selection strategy.
