How to find id in an array that is inside of an array of objects

Example:

let arrayobjects = [ {      id: 1,      name: "oinoin",      description: ["one", "two", "three"] }, {      id: 2,      name: "zatata",      description: ["four", "five", "six"] } ]; 

How can i find the id of the word "two"??

 


If you need more than one item, you can filter the array via Array#filter, check if property description for each item contains word two via Array#includes (ES7), then map the result to get only id of those items using Array#map.

let arrayobjects = [       { id: 1, name: "oinoin", description: ["one", "two", "three"] },        { id: 2, name: "zatata", description: ["four", "five", "six"] } ];  const ids = arrayobjects.filter(item => item.description.includes('two'))                         .map(item => item.id);                          console.log(ids);

If you have only one item, you can just use Array#find and do same checking

let arrayobjects = [       { id: 1, name: "oinoin", description: ["one", "two", "three"] },        { id: 2, name: "zatata", description: ["four", "five", "six"] } ];  const item = arrayobjects.find(item => item.description.includes('two'));                          console.log(item.id);
