Question

My application gathers acceleration 10 times a second, therefore I have a need to store thousands of rows of data. Currently I have an object which is a list of other objects to store it all – anything more efficient than that?

var arr = [];

function dataPoint(x, y, z, tstamp) {
    this.xAccel = x;
    this.yAccel = y;
    this.zAccel = z;
    this.epoch = tstamp;
}

var dp = new dataPoint( acceleration.x, acceleration.y, acceleration.z, acceleration.timestamp );

arr.push(dp);

If the platform you’re targeting supports typed arrays then those would probably be more efficient.
