I would humbly suggest not using const unless it's for a value where the variable name would normally be in ALL_CAPS. Const reduces the code's readability - as one is mentally parsing the code, seeing const makes you stop and think, "ooh, this is special and unchanging," only to discover it's just a plain object or function. Just use let unless you really, really need to make sure the value doesn't ever change, and you never want to reassign that variable name.

After I saw that code, I immediately checked for const usage in JS. Definitely caused a confusion for me. So, +1 for this.
