# github-linguist

💻 Counts the number of lines of code, written in TypeScript.

**Warning:** This package uses regular expressions to approximate the lines of code in a project. The
results are not 100% precise because the regular expressions can return mistakes in edge
cases, for example if comment tokens are present inside of multiline strings.
