Actually I redact that approval since there's one that also uses const, see #691 |

Requirements
Description of the Change
Use "let" instead of "var" to define loop variables.
Alternate Designs
I can't see any other approaches.
Benefits
Defining loop variables with "var" can lead to unwanted side effects. Therefore it is recommended to use "let".
Possible Drawbacks
There might be some developers who are not using ES6, like very old legacy versions of node.js. I believe node.js uses "let" since version 4.0.
Applicable Issues
At some point, we will have to switch to "let". The question is: when, if not now?
