It's called 'delay'.
What does the delay keyword ?
The delay keyword does nothing more than stop the execution of the current
stack and immediately continues to the next task in the queue. But that's
not all! Instead of discarding the stack, it adds it to the end of the
queue. After all tasks before it are done, the stack continues to execute.
What is it good for?
delay could help make blocking code non-blocking while it still looks like
synchronous code. A short example:
delay; //since there is currently another task in the queue, do this
task first before continuing
//Outputs: one, two, three
This simple keyword would allow us to create a synchronous-looking code
wich is asynchronous behind the scenes. Using node.js modules, for example,
would no longer be impossible to use in the browser without trickery.
There would be so many possibilites with such a keyword!
do to bring this into the new ECMAscript Specification?
Please disuss as much as you want! :)
