What is the best way to arrange an array of objects in a descending order in Angular?

  private sumArray : any = [];
  private sortedArray : any = [];
  private arr1 =['3','2','1'];
  private arr2 = ['5','7','9','8'];
  
  constructor(){}

  ngOnInit(){
     this.sumArray = this.arr1.concat(this.arr2);
     this.sortedArray = this.sumArray.sort((a, b) => parseInt(b) - parseInt(a));
  }

Answer №1

To organize the array, simply provide a function to the sort method

.sort((a,b) => b - a)

Try it out on StackBlitz

Answer №2

Your solution

By using the code above, you can sort the array in ascending order.

If you want to sort the array in descending order, you'll need to provide a comparator function.

To sort in descending order, use this.display = this.addition.sort((a,b) => b - a);
