[FIXED] how to iterate over object and dynamically assign values to keys

Issue

Hella all,

so I am struggling with the following problem: I have an object with some keys and values. I would like to take them out and make a new array of objects. Here is the code, as it describes my problem better.

const sourceObj = {
  test1: "a",
  test2: "b",
  test3: "c",
  test4: "d",
  test5: "e"
};

const myTable = [];

for (let value of sourceObj) {
  for (let i = 1; i < 6; i++) {
    const targetObject = {
      foo: "foo",
      year: value.test + i,
      bar: "bar"
    };
    myTable.push(targetObject);
  }
}

console.log(myTable);

// expected output
// [
//   {
//     foo: "foo",
//     year: "a",
//     bar: "bar"
//   },
//   {
//     foo: "foo",
//     year: "b",
//     bar: "bar"
//   },
//   ...
//   {
//     foo: "foo",
//     year: "e",
//     bar: "bar"
//   },
// ]

Solution

you can iterate on object keys and use method array.map to get the expected object

const sourceObj = {
  test1: "a",
  test2: "b",
  test3: "c",
  test4: "d",
  test5: "e"
};

const myTable = Object.keys(sourceObj).map((key) => {
  return {
      foo: "foo",
      year: sourceObj[key],
      bar: "bar"
    };
});

console.log(myTable);
