Example 1: javascript sort array of objects
const books = [
{id: 1, name: 'The Lord of the Rings'},
{id: 2, name: 'A Tale of Two Cities'},
{id: 3, name: 'Don Quixote'},
{id: 4, name: 'The Hobbit'}
]
compareObjects(object1, object2, key) {
const obj1 = object1[key].toUpperCase()
const obj2 = object2[key].toUpperCase()
if (obj1 < obj2) {
return -1
}
if (obj1 > obj2) {
return 1
}
return 0
}
books.sort((book1, book2) => {
return compareObjects(book1, book2, 'name')
})
Example 2: javascript sort array of objects by key value
arr.sort((x, y) => x.distance - y.distance);
Example 3: array sort by key javascript
function sortByKey(array, key) {
return array.sort((a, b) => {
let x = a[key];
let y = b[key];
return ((x < y) ? -1 : ((x > y) ? 1 : 0));
});
}
Example 4: javascript sort array of object by property
function sortByDate( a, b ) {
if ( a.created_at < b.created_at ){
return -1;
}
if ( a.created_at > b.created_at ){
return 1;
}
return 0;
}
myDates.sort(sortByDate);
Example 5: sort array of objects javascript by key value
myArray.sort(function(a, b) {
return a.distance - b.distance;
});
Example 6: js sort array of object by key
function dynamicSort(property) {
var sortOrder = 1;
if(property[0] === "-") {
sortOrder = -1;
property = property.substr(1);
}
return function (a,b) {
if(sortOrder == -1){
return b[property].localeCompare(a[property]);
}else{
return a[property].localeCompare(b[property]);
}
}
