LGTM One thing we might want to consider while moving forward with block scoping is that we don't need to use IIFEs. The changes in this PR could just be wrapped in curly braces and create a new block scope. |
|
@silverwind It is already supported in strict mode. |
|
Oh, I never knew, thanks! |
|
@silverwind I think it's just part of the definition of block scope. It works at least back to io.js v1.0.0. |
|
So called standalone blocks seem to have been around since JavaScript 1.0 according to MDN. It's the combination of strict mode creating a scope on them and block scoped vars that makes them useful now. |
`test-assert.js` redeclares a variable with `var`. This change converts it to a `const` declaration and wraps it in a standalone block to scope it to just the test that uses it.

I sure like the idea of not having the creation of a function as unnecessary overhead. Converted to block scope, force pushed, looks good. |

Added the lts-watch-v4.x label. For commits like this, getting them on the lts-watch list for v4.x helps significantly when determining which commits need to be cherry picked. We cherry pick almost all the test commits unless they specifically relate to semver-minor/major updates. |
