make（[] string）和[] string {}有什么区别

I make global declaration of a value.

var {
     b = make([]string,10)  //way 1
     a = []string{}         //way 2
}

Both ways work. Can someone make detailed explanation of the difference between them?

The expression make([]string,10) returns a slice with length and capacity of 10. The expression []string{} returns a slice with length and capacity of 0.

Check it out on the playground.
