How to combine Javascript arrays and objects?

expected

newArray = [ {name: xyz}, {name: abc}, {name: def}, {name: ghi}, {name: jkl} ]

Answer 1

You can flat the array

const oldArray = [
  [{ name: "xyz" }, { name: "abc" }, { name: "def" }],
  [{ name: "ghi" }, { name: "jkl" }],
];

const result = oldArray.flat();

console.log(result);
