I have an array of objects with different keys I want to move the objects to the top based on the key I want.
Given array based on the status: "Active" I want all the matched objects to be moved top
[
{name: "abc", age: "20", status: "Active"},
{name: "xyz", age: "21", status: "Inactive"},
{name: "pqr", age: "22", status: "Active"}
]
Expected Output:
[
{name: "abc", age: "20", status: "Active"},
{name: "pqr", age: "22", status: "Active"},
{name: "xyz", age: "21", status: "Inactive"}
]
let list = [{
name: "abc",
age: "20",
status: "Active"
}, {
name: "xyz",
age: "21",
status: "Inactive"
}, {
name: "pqr",
age: "22",
status: "Active"
}]
list.sort((a, b) => (a.status !== "Active") ? 1 : -1)
console.log(list)Produces the following output
[
{ name: 'pqr', age: '22', status: 'Active' },
{ name: 'abc', age: '20', status: 'Active' },
{ name: 'xyz', age: '21', status: 'Inactive' }
]
Arrays have method Array.sort where you can pass function that return 1, -1 or 0 which corresponds to how to move element of an array
const arr = [{
name: "abc",
age: "20",
status: "Active"
}, {
name: "xyz",
age: "21",
status: "Inactive"
}, {
name: "pqr",
age: "22",
status: "Active"
}]
console.log(arr.sort((a, b) => (a.status === b.status) ? 0 : a.status === "Active" ? -1 : 1))you can change your code like this.
function handleData(arr, status) {
if(!arr || arr.length == 0) return
for(let i=0; i<arr.length; i++) {
let item = arr[i];
if(item.status == status) {
arr.splice(i, 1);
arr.unshift(item)
}
}
}
let arr = [{name: "abc", age: "20", status: "Active"}, {name: "xyz", age: "21", status: "Inactive"}, {name: "pqr", age: "22", status: "Active"}]
handleData(arr, 'Active')
