How to find the sum of elements in an array in angular. In the typescript code below, typescript has an inbuild reduce method to get the sum of array elements. A reduced method reduces the array to a single value.

Sample Script

this.subTotal = this.salesReturnDetail.reduce((sum,current)=> sum   current.ReturnTotal,0);
                    

reduce takes two parameters

array.reduce(callback[, initialValue]);
callback - Function to execute on each value in the array.
initialValue - Object to use as the first argument to the first call of the callback.
