Loop through an array of objects and create a new object

Question

I have an array of objects, each object has a title, content and contentHTML. I want to map over this array and create a new object. The new object will take the value of the title property and use this as the parent property for each of the content and contentHTML properties. The code below only seems to be getting the last object in the array.

The results is:

{
  "sidebar": {
      "text": "Some sidbar text here",
      "content": "<p>Some sidebar text here</p>"
    }
}

The expected result is:

{
    header: {
        text: "Some header text here",
        content: "<p>Some header text here</p>"
    },
    footer: {
        text: "Some footer text here",
        content: "<p>Some footer text here</p>"
    },
    sidebar: {
        text: "Some sidbar text here",
        content: "<p>Some sidebar text here</p>"
    }
}

var originalObj = [{
    title: "header",
    content: "Some header text here",
    contentHTML: "<p>Some header text here</p>"
  },
  {
    title: "footer",
    content: "Some footer text here",
    contentHTML: "<p>Some footer text here</p>"
  },
  {
    title: "sidebar",
    content: "Some sidbar text here",
    contentHTML: "<p>Some sidebar text here</p>"
  }
];
let newObject = {};
for (let item of originalObj) {
  var tempObj = {
    [item.title]: {
      text: item.content,
      content: item.contentHTML
    }
  };
  newObject = tempObj;
}
console.log(newObject);

You are overwriting your object with new value every time you're doing

var tempObj = {//object keys}

Use spread operator to copy the previous values. Spread operator loops through objects iterable values and expands them.

var originalObj = [
    {
        title: "header",
        content: "Some header text here",
        contentHTML: "<p>Some header text here</p>"
    },
    {
        title: "footer",
        content: "Some footer text here",
        contentHTML: "<p>Some footer text here</p>"
    },
    {
        title: "sidebar",
        content: "Some sidbar text here",
        contentHTML: "<p>Some sidebar text here</p>"
    }
];

let newObject = {};
for (let item of originalObj) {
    newObject = {
        ...newObject,
        [item.title]: {
            text: item.content,
            content: item.contentHTML
        }
    };
}
console.log(newObject);
