I rewrite your example using harmony-proxy and node-fibers:
======================================================
require( 'jin' )( function( $ ){
var add= $.jin.sync( function( x, y, done ){
console.log( 'add', x, y )
setTimeout
( function( ){
done( null, x + y )
}
, 10
)
} )
var div= $.jin.sync( function( x, y, done ){
console.log( 'div', x, y )
setTimeout
( function( ){
if( y == 0 ) throw new Error( 'Division by zero' )
done( null, x / y )
}
, 10
)
} )
try {
console.log( 'first:', div( add( 5, 3 ), add( 1, 3 ) ) )
console.log( 'second:', div( 10, add( 1, -1 ) ) )
} catch( error ){
console.log( error )
}
}
======================================================
Output:
add 5 3
add 1 3
div 8 4
first: 2
add 1 -1
div 10 0
Error: Division by zero
