Question

i have problem with my javascript project. i have an array with value like this :

exmpArr = ["PX1","PX2","PX3"];

and i want to loop and push it to obj like this:

sections = [
            {
             rows: [
              { title: exmpArr[i], rowId: exmpArr[i] },
              ],
            },
           ];

the final value must like this:

sections = [
            {
             rows: [
              { title: "PX1", rowId: "PX1" },
              { title: "PX2", rowId: "PX2" },
              { title: "PX3", rowId: "PX3" },
              ],

map returns a new array from the one you're mapping over. So you can immediately assign that array as the property value when you build your object.

const exmpArr = ['PX1', 'PX2', 'PX3'];

const sections = [
  {
    rows: exmpArr.map(el => {
      return { title: el, rowId: el };
    })
  }
];

console.log(sections);
