Example of using Array.prototype.some in a sequential flow control fashion

gistfile1.js

//following functions would perform some operations, which would either succeed or fail,
//which would be indicated by the function returning true or false
function a() {
    //do something which returns true or false
}

function b() {
    //do something which returns true or false
}

function c() {
    //do something which returns true or false
}

//The functions would need to be called in sequence, but if one of them succeeds, the rest should not be executed.
//We can use some() for this quite nicely:
[a, b, c].some(function(worker) {
    var result = worker();

    if(result) {
        //some action here that needs to happen once one of the ops succeeds
    }

    return result
})

//some() will keep calling the functions in order until one of them returns true, or until they have all been called
