Shouldn't binance.depth return data as array?

Title

• enhancement: binance.depth should return data as array

Short Description:

• Currently, binance.depth returns an object, but it seems more like array data. Not to be finicky or anything. Just asking.

Rather, depth data should be returned as an array. E.g.

{
  bids: [
    [0.00022997, 49.00000000],
    [0.00022867, 11.00000000],
    [0.00022865, 1149.00000000],
    [0.00022810, 20.00000000]
], asks: [
]

Platform:

• MacOS

node version:

• v10.0.0

code

binance.depth("BNBBTC", (error, depth, symbol) => {
  console.log(symbol+" market depth", depth);
});

Thank you, supercoder!! ;)

I had found that managing the depth cache as an object was way more efficient in terms of speed. However if you prefer the array format you can still request it as such:

binance.websockets.depthCache(['BTCUSDT'], (symbol, depth) => {
    const limit = 3;
    let bids = binance.sortBids(depth.bids, limit);
    let asks = binance.sortAsks(depth.asks, limit);

    //console.log("best bid: "+binance.first(bids));
    //console.log("best ask: "+binance.first(asks));
    let output = {bids:binance.array(bids), asks:binance.array(asks)};
    console.log(symbol, output);

    // save information to json file
    //file.writeFile("json/depth/"+symbol+".json", JSON.stringify(output, null, 4), (err)=>{});
});
