------------------------------------------------

As a small white to see this piece of code is a face of the currency, and now understand to do an analysis.

1.series after the flag1:function format expression is this is a JSON element whose name is Flag1 specific content is the colon after the

What does the content behind 2.FLAG1 mean to be taken out alone?

function (done) {//FLAG1 is a process ID, user-defined
Logical processing
Done (NULL, "return result")//The first parameter is an exception error, the second parameter returns the result
}

Later, it is understood that the arguments passed in after function can be a function, so what it means to do (null, "return result") is to call the function and pass in 2 parameters to simulate the next process.

The function is named one and two respectively.

So it becomes a call to the function to pass in the parameter one and the other is actually a function.

(one);

function One (b,a)
{
Console.log (a);
}

function (done) {//FLAG1 is a process ID, user-defined
Logical processing
Done (NULL, "return result")//The first parameter is an exception error, the second parameter returns the result
};
