You will spend more time at the beginning but the learning curve is worth it.
Typescript + Eslint makes you a better developer I reckon. Forces you to code cleanly following standards so it's easier for someone else to join in later on or even for you to revisit old codes. As for Typescripts it will help reducing silly bugs such as passing the wrong parameter to a function or sending incomplete object to a method.
Everything becomes stricter, which can be annoying but in the long run you'll discover their usefulness.
