Spawning a void function to run concurrently
In this section, we will write a simple function that does not have any return type. The function just prints a message to the console. Then, we will spawn this function so that it runs in a concurrent thread using the go keyword, as follows:
module main
fn greet() {
println('Hello from other side!')
}
fn main() {
h := go greet()
println(typeof(h).name) // thread
}
In the preceding code, the h variable provides access to handle the concurrent task. The h variable is of the thread type in the preceding code. The output of the preceding code could be any of the following outputs:
The following is the first output you may receive:
thread
The following is the second output you may receive:
thread Hello from other side!
You will see either of these outputs, which appear to be inconsistent outcomes from the program. Notice that the greet() function...
