Building an efficient Logger in TypeScript

June 30, 2019  6 minute read  

Just about every project needs a logging system. In the early days of development, you need to output data to the console so you aren’t setting breakpoints in your code all over the place (or you are running the code in the browser, where breakpoints are more difficult).
