What Is More Compute Efficient Between Golang's If and Switch Statements


I am curious to know which between the two is more efficient and how they work under the hood.

Thanks in advance.

You can find out for yourself using the Compiler Explorer (godbolt): https://godbolt.org/z/qrYGzMjWd Looks to me as if If is more efficient here.

it's unlikely that there is a difference

compilers are usually optimizing these kind of statements so they end up similar or identical

if you wanna be sure, make two loops running a few million times with random if else / switches and time them
