Remove from array

[nrukavkov]

Following the instruction, we can add to the array. But I could not find a way how to remove an element from array.

// push stuff to an array for a particular key
    await db.push("transformers", "optimus prime");
    await db.push("transformers", "bumblebee");
    await db.push("transformers", "iron hide");

Sure, thanks for the suggestion, I'll add it!

I just use something like this:

const transformers = await db.get("transformers");
const transformerToRemove = "optimus prime";
await db.set(`transformers`, transformers.filter(transformer=> transformer !== transformerToRemove))

Is anyone interested in implementing this feature resulting in a Hacktoberfest PR? ;)

jsoning.prototype.remove = async function(key, callback) {
  const array = await this.get(key);
  return this.set(key, array.filter(item => !callback(item)))
};

await db.remove('jobs', (job) => {
  return job.id === 'xxxxxxx';
});

jsoning.prototype.update = async function(key, callback) {
  const array = await this.get(key);
  return this.set(key, array.map(item => callback(item) || item))
};
await db.update('jobs', (job) => {
  if(job.id === 'xxxxxxx') {
    return {
      ...job,
      ...params,
    }
  }
  return job;
});
