As far as my editor is concerned, everything's fine there, but I can use ESLint to check if the direction of my iterator change makes sense given my condition. To do that, I use the for direction rule. Over in my ESLint rc file, I'll add for direction with the value of error. So that's in the rules section, and for dash direction, and error. Saving that, I'm going to go back to index.js and I have a new error flagged. So, if I move the pointer over that that tip text is going to point out that the update clause moved the variable in the wrong direction. So, my code starts at 10, and it checks for a value greater than zero, and increasing I after each loop. That creates an infinite loop, because I will never satisfy that ending condition. I'm…
