Instead of using curly braces {} for "i" you should use brackets []. Also, in your for statement, you should declare the variable first and then use semicolons between the pieces instead of commas. As Steven noted below, you also need to pluralize temperatures in the iteration. Try this:

var temperatures = [100,90,99,80,70,65,30,10];
for (let i=0; i<temperatures.length; i+=1) {

There's a few issues:

  • the loop variable should be explicitly declared (using "var" or "let")
  • the array name is "temperatures" (plural), not "temperature" (singular)
  • the clauses of the "if" statement should be separated by semicolons instead of commas
  • indexing is done with brackets [] instead of braces {}
