I'm dependent on Jetbrains IDE for most of my work. It really shines in showing the user best practices and recommendations. A lot of the programming concepts are same across languages and this IDE helps you find the right function/method with its suggestions. And at least for java it'll suggest you variable names, it'll suggest you if a loop can be converted to a stream, it can generate templates for unit tests, it can tell you if a variable might be null, etc. There are a ton of small small features that all add up to a great experience. 10/10 would recommend for a new programmer.
