Haskell like do-syntax for JavaScript
##Example
###List monad
var
doSyntax = require('do-syntax'),
xs = [1,2],
ys = eval(doSyntax.syntax)(doSyntax.listM, function () {
x1 <- xs;
x2 <- xs;
return pure([x1, x2]);
});
console.log(ys); // [[1,1],[1,2],[2,1],[2,2]]###Async Monad
var
fs = require('fs'),
doSyntax = require('do-syntax');
eval(doSyntax.syntax)(doSyntax.asynxM, function () {
file1 <- async(fs.readFile)('file1.txt', 'UTF-8');
file2 <- async(fs.readFile)('file2.txt', 'UTF-8');
console.log(file1 + file2);
return pure();
})(function (err) {
//error callback
console.log(err);
});
