lodash filter by name

I'm trying to figure out how to use lodash to filter the following object:

contacts = {
  A: [
  { name: "Albert", age: 16 },
  { name: "Arthur", age: 24}
  ],
  B: [
  { name: "Bob", age: 33 }
  ],
  C: [],
  D: [],
...
};

I'd like to be able to filter contacts by name (contains) while keeping the same structure, I don't know to tell lodash to look for any objects on the 2nd level.

Any idea how to go about this?

Solution

  • Try this one

    const contacts = {
  A: [
  { name: "Albert", age: 16 },
  { name: "Arthur", age: 24}
  ],
  B: [
  { name: "Bob", age: 33 },
  { name: "Ahn", age: 20 },
  ],
  C: [],
  D: []
};

const obj = {};
Object.keys(contacts).forEach(index => {
  obj[index] = contacts[index].filter(person =>
    person.name.includes("th"));
});
console.log(obj);
