Tips for golfing in Proton Proton is a quite new language created by PPCG user Hyper Neutrino.

It is very similar to Python, and has similar syntax to the language Cheddar, hence there are some clever tricks you can use in order to reduce your byte count. Let's get those cool tricks listed here. As usual, please post one tip per answer and avoid obvious things (e.g. remove spaces). If you have any further questions about any of the tips listed, there is a dedicated chat room for Proton.
Use currying when you need a lambda with 2 arguments
If you want a function with 2 arguments, currying syntax always saves 1 byte. For example:
f=(a,b)=&gt;a+b

Is one byte longer than:
f=a=&gt;b=&gt;a+b

The first function can be called with f(number_1, number_2), whilst the latter is called using f(number_1)(number_2).
