I have an array that looks similar to this,
[
{ 'name': 'Bob', 'age': 25, 'sex': 'M' },
{ 'name': 'Gill', 'age': 33, 'sex': 'F' },
{ 'name': 'Glen', 'age': 55, 'sex': 'M' },
{ 'name': 'Flo', 'age': 19, 'sex': 'F' }
]
I have another array of objects that looks like this,
[
{ 'name': 'Fred', 'age': 49, 'sex': 'M' },
{ 'name': 'Thelma', 'age': 27, 'sex': 'F' }
]
I want to add this second of objects to my first array so the first array would look like this,
[
{ 'name': 'Bob', 'age': 25, 'sex': 'M' },
{ 'name': 'Fred', 'age': 49, 'sex': 'M' },
{ 'name': 'Thelma', 'age': 27, 'sex': 'F' }
{ 'name': 'Gill', 'age': 33, 'sex': 'F' },
{ 'name': 'Glen', 'age': 55, 'sex': 'M' },
{ 'name': 'Flo', 'age': 19, 'sex': 'F' }
]
So I thought it would be case of doing,
originalPeople.splice(1, 0, newPeople)
But when I console.log my originalPeople array doing this, I get the following similar output,
{ 'name': 'Bob', 'age': 25, 'sex': 'M' },
ƒ newPeople(),
{ 'name': 'Gill', 'age': 33, 'sex': 'F' },
{ 'name': 'Glen', 'age': 55, 'sex': 'M' },
{ 'name': 'Flo', 'age': 19, 'sex': 'F' }
I assume you can splice an array objects into an array and I have to do something different?
Use spread operator to add newPeople (see code below)
let originalPeople = [
{ 'name': 'Bob', 'age': 25, 'sex': 'M' },
{ 'name': 'Gill', 'age': 33, 'sex': 'F' },
{ 'name': 'Glen', 'age': 55, 'sex': 'M' },
{ 'name': 'Flo', 'age': 19, 'sex': 'F' }
]
let newPeople = [
{ 'name': 'Fred', 'age': 49, 'sex': 'M' },
{ 'name': 'Thelma', 'age': 27, 'sex': 'F' }
]
originalPeople.splice(1, 0, ...newPeople)
console.log(originalPeople)
could this be useful?
var arr1 = [
{ 'name': 'Bob', 'age': 25, 'sex': 'M' },
{ 'name': 'Gill', 'age': 33, 'sex': 'F' },
{ 'name': 'Glen', 'age': 55, 'sex': 'M' },
{ 'name': 'Flo', 'age': 19, 'sex': 'F' }
]
var arr2 = [
{ 'name': 'Fred', 'age': 49, 'sex': 'M' },
{ 'name': 'Thelma', 'age': 27, 'sex': 'F' }
]
arr1.push(...arr2);
console.log(arr1)
