Any implementation works poorly, each approach has different problems
this example by https://www.espruino.com/DS18B20

owMultiSensors = new OneWire(D4);
DSlib = require("DS18B20") ; 
var sensors = owMultiSensors.search().map(function (device) {
    return DSlib.connect(owMultiSensors, device);
  });
 
  setInterval(function() {
    sensors.forEach(function (sensor, index) {
    sensor.getTemp(function (temp) {
      console.log(index + ": " + temp + "°C");
    });
  });

}, 1000);

After several seconds the error:

ASSERT(jsvGetLocks(var) < 15) FAILED AT src/jsvar.c:721
  #1[r3,l2] Object {
    #2[r1,l2] ASSERT(jsvGetLocks(var) < 15) FAILED AT src/jsvar.c:701
HALTING.

If sensors search put to set Interval this problem disappears , but other appears

owMultiSensors = new OneWire(D4);
DSlib = require("DS18B20") ; 
setInterval(function() {
  var sensors = owMultiSensors.search().map(function (device) {
    return DSlib.connect(owMultiSensors, device);
  });
    sensors.forEach(function (sensor, index) {
    sensor.getTemp(function (temp) {
      console.log(index + ": " + temp + "°C");
    });
  });
}, 1000);

This code fills all RAM in time and device stops working
Interval time increase does not have any influence, it only delays the time of crash
