Debug mongodb - ReferenceError: Console not defined

I got the file js

to work in mongodb

, where I got the console.log

debug expression :

use test;
db.city.find().snapshot().forEach(function(city){
    var Pos = city.Pos;

    if (Pos) 
    {
        longLat = Pos.split(" ");
        console.log("longLat");  // for debugging ----------------------------  
        console.log(longLat);

        lon = longLat[0];
        lat = longLat[1];

        if (lon && lat)
        {
            lon = parseFloat(lon);
            lat = parseFloat(lat);
            longLat = [lon, lat];
            city.longLat = longLat;

        }

    }
    db.orgs.save(city);

})

When I ran it ...

mongo < /path/to/this/js/file.js

... I got an error in the output:

ReferenceError: console is not defined

Is there a way to log intermediate results for debugging purposes?

Use methods print

or printjson

. They are used for emitting like console.log () inside a shell:



    if (Pos) 
    {
        longLat = Pos.split(" ");
        print("longLat");  // for debugging ----------------------------  
        printjson(longLat);
