Problem Statement:
Attempts to obtain an element by its class name using the syntax "document.getElementByClass()" result in an "getElementByClass is not a function" error.
Answer:
To successfully access an element by its class, the proper DOM function to employ is "getElementsByClassName," accommodating the possibility of multiple elements sharing the same class. This function returns a NodeList, which can be further manipulated as needed.
Alternative Approaches:
For improved compatibility and performance, consider utilizing querySelector('.foo') or querySelectorAll('.foo'), as recommended by caniuse.com.
