Common variables declaration syntax

[lucasmenendez]

Golang provides three syntaxes for the variable declaration:

• The most comfortable way is foo := "foo" but with this syntax you probably makes mistakes like binary_address := []byte{0} (wallet.go:62) or s := "" (transaction.go:70).

• Other way consists in using the keyword var to the memory allocation and waits for the compiler to infer the variable type from the right side of declaration: var foo = "foo". I think its better way that the first one because allows to the developer to allocate memory without occupying them.

• The last way its an extended version of the second one that includes variable type: var foo string = "foo". This way forces the developer to write more code, but make it more legible (and it's my favorite way).

What do you think about it?
