Array Addition Doesn't Run Correctly - JavaScript
Hello everyone,
I want to ask why the following code doesn't return the largest number in the array? When I break the code down into it's simpler components it all works fine. However, when I put it together, it gives me the wrong answer. Any insight would be appreciated. Thank you.
function ArrayAdditionI(arr) {
var largest = 0;
for(var i = 0; i < arr.length; i++){
if(arr[i] > largest){
largest = arr[i];
}
}
return largest
}
//console.log(ArrayAdditionI(1,2,3,5)):
//returns 0 instead of 5

this code does work.
you are not passing the function an array. You are passing in several parameters.
console.log( ArrayAddition( [1,2,3,4,5] )
when you do this
console.log( ArrayAddition( 1,2,3,4,5 )
the function takes the first parameter 1 and uses that number as your arr variable. Thus returning 0 because numbers have no length, the loop does not trigger.
Javascript functions don't have a fixed parameter list. So you can pass in as many as you like.
someFunction( param1, param2, param3, param4, param5 .....paramN )
