I need to join data from 2 array
example data:
const data1 = [ {"firstName":"Donald"}, {"firstName":"Mickey"} ] const data2 = [ {"lastName":"Duck"}, {"lastName":"Mouse"} ] the result i want is:
const final = [ {"firstName":"Donald", "lastName":"Duck"}, {"firstName":"Mickey", "lastName":"Mouse"} ] how to do that?
const data1 = [ {"firstName":"Donald"}, {"firstName":"Mickey"} ] const data2 = [ {"lastName":"Duck"}, {"lastName":"Mouse"} ] const result = data1.map((obj, index) => ({ ...obj, ...data2[index] })); console.log(result);
You can also do with a for loop:
let finalRes = []; const data1 = [{ firstName: "Donald" }, { firstName: "Mickey" }]; const data2 = [{ lastName: "Duck" }, { lastName: "Mouse" }]; for (var i = 0; i < data1.length; i++) { finalRes.push({ ...data1[i], ...data2[i] }); } console.log(finalRes);
const data1 = [{ "firstName": "Donald" }, { "firstName": "Mickey" } ] const data2 = [{ "lastName": "Duck" }, { "lastName": "Mouse" } ] const result = []; data1.forEach((aData, index) => { result.push({ ...aData, ...(data2[index]) }) }) console.log(result);
