new to ng4/typescript and having some difficulty. How do I sum the items in an array?
Added screenshot of what it looks like in action for example
for (let card of this.cards) {
for (let val of card.cards){
if(val.value == "JACK"){
val.value = 10;
}
if (val.value == "QUEEN"){
val.value = 10;
}
if (val.value == "KING"){
val.value = 10;
}
if (val.value == "ACE"){
val.value = 10;
}
this.hand = Number(val.value) + Number(val.value); (I'm sure this is wrong)
}
}
Use Array#Reduce :
// Array of numbers var array = [1,2,3,4,5]; var sum = array.reduce((acc, cur) => acc + cur, 0); console.log(sum) // Array of strings var toNumber = ['1','2','3','4','5']; var sumNumber = toNumber.reduce((acc, cur) => acc + Number(cur), 0) console.log(sumNumber);
let sum = array.reduce(function (acc, cur) { return acc + cur; });
