[8Observer8 27]

Hello

Please, help me to understand what does mean '_' in this JavaScript code. I took this pease of code from here

 

    function createPoints(spawnBehavior)
    {
        var ret = new THREE.Geometry();
 
        _.times(mode.particleCount, function (index)
        {
            ret.vertices.push(spawnBehavior(index));
        })
 
        return ret;
    }

Could also be lodash

It could actually be anything, JS variable assignment being what it is. _ just references an object, by convention, this has been 'claimed' by underscore, and then lodash, but also used by some functional libraries too (in the same way jQuery has claimed $), there's no formal claiming here, they just assign their libraries to this identifier, if you included two libraries that try to assign to the same identifier (such as underscore and lodash, not that you'd ever want to) then they'll clash and only one will get the reference.

As you've dug through the includes and found lodash, its pretty safe to assume that it refers to that library.
