Can someone help me by explaining what I missed and a bit of contextual explanation?

Had some trouble converting this into a for loop. Would like some assistance also in doing this as while loop as well.

script.js 
var temperatures = [100,90,99,80,70,65,30,10];

for (var i = 100,90, 99, 80, 70, 65, 30, 10 ) {
  i = temperatures 
}
console.log(temperatures);

Here's a few hints:

  • "for" loops have 3 clauses, separated by semicolons
  • the 3 clauses are initialization, condition, and increment
  • your loop can simply count from 0 up to the length of the array
  • your loop variable can be used as an array index to get a value from the array
  • the log function call should be inside the loop
