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).
