// coding: utf-8

// example 1
// string length
// given the following string, 'this example string', write the string length to the console

 
var string = 'this example string';
console.log(string.length);



// example 2 - arrays 
// write a function to 'sum' the values in array 
// times and print the variable totals to the console
// you can use a for-loop or for-each loop

times = [3.25, 4.75, 2.50, 3.00, 1.00, 0.50, 1.50]
var sum = 0;
for(int i=0; i<times.length;i++) {
  sum += times[i];
  console.log('Sum is: ' + sum);
}

// example 3
// for-loop
// loop total and sum to limit

var total = 0;
var limit = 10;
for(int i=total; i<limit; i++) {
  total += i;  
}
console.log('Total is: ' +total);

// example 4 - for-each array
// write a for-each function to add the trading pairs to list symbols 
// and write the value for symbols to the console

pairs = ["btcusd","ethusd","ltcusd","adabtc","xlmusd","doge"]
symbols = [];
pairs.forEach(function(obj) {
  symbols.push(obj);
})
console.log('Symbols array: ' + symbols.toString());

// example 5 - json list
// write a function to write the 'key' value to the console

var keypairs = [{
    "key": "adMidServer",
    "value": "ChampioneBridge",
    "correlation_id": "51e57d4cd7e9a3d3e37c1790c1c7b6d2e25d0e091af12e88a19cd00c64bf5b51"
},
{
    "key": "adServer",
    "value": "STACD001",
    "correlation_id": "d1b55ee2d83fcd4d5a77a608869f1247d5ba7c0d81cc74d44081161044dddbe5"
},
{
    "key": "MailServer",
    "value": "smtp.systemic.us",
    "correlation_id": "cf07f38a39e8eb602b182e1162777f7f486091c38b5eab5019babf6f66c1f191"
}];


for(var i=0; i<keypairs.length;i++){
	console.log(keypairs[i].key); 
}
