Reduce Method for Arrays

const items=[
   { name:'Bike' , price:100} ,
   { name:'TV' , price:200} ,
   { name:'Album' , price:10} ,
   { name:'Book' , price:5} ,
   { name:'Phone' , price:500} ,
   { name:'Computer' , price:1000} ,
   { name:'Keyboard' , price:25}

]

const total=items.reduce((currentTotal , item)=>{
    //it takes an item and a property we want to reduce to
    //a second parameter is a starting point in this case 0

    return item.price + currentTotal;

},0)
console.log(total);
//reduce method runs a function on every membr of the array
//the first member of that function(currentTotal) is going to be whatever the previous iteration of this array returned
//the second item(item) is the actual item in the array
//the currentTotal is going to start on the very first iteration with whatever we pass in as a second parametar(this case 0)
