DEBUG_MIME doesn't work

[dougwilson]

It throws ;)

$ DEBUG_MIME=1 node -pe 'require("mime");0'

node_modules\mime\mime.js:26
        console.warn(this._loading.replace(/.*\//, ''), 'changes "' + exts[i]
                                   ^

I was trying to figure out what MIME was doing, and noticed some strange usage within the DEBUG_MIME section..

Ironically, it actually failed where @dougwilson has listed.. But even if it didn't, I think it would have failed in a different place if I am reading this correctly.

if (process.env.DEBUG_MIME && this.types[exts]) {
    console.warn(this._loading.replace(/.*\//, ''), 'changes "' + exts[i] + '" extension type from ' +
    this.types[exts] + ' to ' + type);
}

Correct me if I am wrong, but should this.types[exts] not be this.types[exts[i]] Since exts is an array, not a string. It's fine if the array is singular since ["foo"] resolves to "foo", but ["foo", "bar"] resolves to "foo,bar" and so would never be caught correctly.

I think I will make a Pull Request for this.
