How to Sort Array of Objects in JavaScript |
In JavaScript, you can use the built-in sort() method to sort an array of objects based on a specific property. Here's how you can do it:
The sort() method takes a function as an argument that defines the sorting order. The function takes two parameters, a and b, which represent two objects in the array. The function returns a negative value if a should come before b, a positive value if a should come after b, and 0 if they are equal.
In this example, the sorting function subtracts the age property of b from the age property of a. This results in a negative value if a has a smaller age than b, which means that a should come before b in the sorted array.
To sort the array by age in descending order, you can simply reverse the order of a and b in the sorting function:
This will subtract the age property of a from the age property of b, resulting in a positive value if a has a smaller age than b, which means that b should come before a in the sorted array.
You can also sort an array of objects based on other properties by modifying the sorting function accordingly.
This uses the localeCompare() method to compare the name properties of a and b and returns a negative, zero, or positive value depending on the order of the strings.
Note that the sort() method sorts the original array in place, so be careful not to overwrite your original data.
