Likes:

• Async programming: defer
  
• Goroutine & channels
  
• Named return values
  
• Length and capacity concept about array
  

Dislikes:

• Go doesn’t support ternary one liners.
  

Instead of:

# Python
return nums[0] if len(nums) != 0 else 0

It has to be:

// Golang
if len(nums) != 0 {
   return nums[0]
} else {
   return 0
}

// Or
if ret := 0; len(nums) != 0 {
   return nums[0]
}
return ret

Lots of discussions about the trade-off of this design: link, link.

Personally I’m still in favor of the Python compact way.

• Get the last element of an array.
  

In Python we can simply use nums[-1] or nums[~0].
But in golang, it has to be: nums[len(nums)-1].

• Reverse a list
  

In Python, reverse an array is as easy as: nums[::-1].

But in golang, you need to wrap up your own tiny function.
As far as I know, no built-in support.

Don't understand why.
