Channels are a type of communication primitive in JuliaLang that allow for the exchange of messages between tasks. They are used to synchronize tasks and to pass data between them.
Example code
# Create a channel
c = Channel()
# Send a message to the channel
@async put!(c, 42)
# Receive a message from the channel
x = take!(c)
println(x)
