Can prettier replace var with let

Question

I am using prettier to format my Typescript code on save. I would like to know if there is an option to replace var with let using prettier.

This is the code I use to format a hole project with

"format": "prettier --write \"src/**/*.ts\" \"src/**/*.js\"",

Prettier is a code formatter. It doesn't do things like that. See "What Prettier is not concerned about" in its docs.
