Is there a method to call only the $values from each rate record in my array that I want to read?
https://i.sstatic.net/MT2XK.png
This is what I have done to access this array:
async ngOnInit() {
this.product$ = await this.reviewService.getReview(this.product.$key);
this.key = Object.values(this.product.reviews);
}
If you want to retrieve an array of rates using the map method and then utilize the reduce function, follow these steps:
ngOnInit():void{
// Extract an array of rates
const rates = yourArray.map(item => item.rate) // rates=[2,3,5,1,..]
// Apply the reduce function to compute the total
const sum = rates.reduce(this.total)
}
private total(total,num){
return total + num
}
