As an expert in the field of programming languages, I can confirm that JavaScript is indeed case-sensitive. This characteristic is important for developers to understand because it affects how they write and use code.

For instance, the variable `myVariable` is different from `MyVariable` and `MYVARIABLE`. This sensitivity to case ensures that each identifier is unique and avoids conflicts. read more >>
