Just uses the flat method.
The flat() method creates a new array with all sub-array elements
concatenated into it recursively up to the specified depth.
const array1 = [
[{
id: 1,
name: "test1",
},
{
id: 2,
name: "test2",
},
{
id: 3,
name: "test3",
},
],
[{
id: 4,
name: "test4",
},
{
id: 5,
name: "test5",
},
{
id: 6,
name: "test6",
},
],
[{
id: 7,
name: "test7",
},
{
id: 8,
name: "test8",
},
{
id: 9,
name: "test9",
},
],
];
let result = array1.flat()
console.log(result);
