この度、freeCodeCampにスタッフとして加わることになりました。
今年の3月頃から日本語翻訳コントリビューターとして活動し始めたのですが、あれよあれよという間に色々と話が進み、自分でもまだ何が起きているのか信じられないような気持ちです。
私自身、約4年前、どうしても開発者・プログラマーになる夢が諦められず、なんとかその道に進む方法を探す中で見つけた教材の一つがfreeCodeCampでした。
まさに、freeCodeCampがなければここにいなかったと思います。
そして、翻訳者というのも頭に浮かんだことのある夢のひとつでした。
その両方に繋がるような、最適な機会に巡り合えたように感じています。
翻訳に限らず、日本語ローカリゼーション、日本語コミュニティの活性化に関わるさまざまな業務を行うことになりそうです。
より、日本でもプログラミング教育にアクセスしやすくなるよう、少しでも力になれればと思います。
MongoDBにこういうデータがあって、findOneでIDを指定してこの1件を取得したい。
{
"_id": {
"$oid": "5f00f8d2e2b54b54646cac19"
},
"title": "new book"
}最初こんな感じで書いてみたけどダメだった。検索結果がnullになってしまう。
var bookid = '5f00f8d2e2b54b54646cac19';
// NG例1
collection.findOne({ "_id": bookid }, function(err, doc){
// do something
}
// NG例2
collection.findOne({ "_id": { "$oid": bookid } }, function(err, doc){
// do something
}I hadn't been doing freeCodeCamp lessons for a while, but finally I earned my Data Visualization certification!
One more certification to go!

I realized that Model.find() in mongoose returns an array of objects [{key: value}] (even if there is only 1 object) but Model.findOne() returns an object {key: value}
This was what I got stuck on Day 71!

Completed user story 3: add an exercise log.
Today I learned:
exports.propertyName instead of module.exports findOneAndUpdate the validation does not work. If I do find and save separately it worked.Now I have done 3/4 of the challenge. 25 more days to go!

Exercise Tracker project. Created a function to get all users.
I accidentally had an unnecessary field indexed as unique (I'm not sure when I did it) and was getting an error on save. I could check and fix that problem on "Indexes" page on mLab.

Thoughts:
It took me so long to figure out the response from mLab DB was not an object { original: "www.google.com" } but an object in an array [{ original: "https://www.freecodecamp.com" }]
I was trying to retrieve the original URL value by result.original or result['original'] but kept getting undefined . I needed to do result[0]['original']
But thinking about callback was fun. It's difficult, but fun.

URL Shortener Microservice
URL Shortener Microservice: Code
Today's Progress:
Thoughts:
I used 'url-regex' library to check if the URL is in a valid format, but it can't be used to check if the URL begins with http(s):// (it accepts URL without http(s):// if it begins with www). So I added a regex to check that part.
function isValidUrl(url) {
// 'url-regex' cannot check if the URL begins with 'http(s)://'
const httpRegex = /^https?\:\/\//i;
// Check if the URL begins with 'http(s)://' AND is in a valid URL format checked with 'url-regex'
return httpRegex.test(url) && urlRegex({exact: true, strict: true}).test(url);

Compared my code and the example code and reviewed on what I thought I didn't understand clearly (where to write the code (which was server.js), callbacks and error handling). The video below helped me.

Finally, I have freeCodeCamp running on my local! There is no first timers welcome issue now but I'm hoping to contribute someday.
I also completed the freeCodeCamp lessons of "Managing Packages with Npm" and "Basic Node and Express" in these 2 days.

These are what the terminal should look like when the npm run commands in the freeCodeCamp installation process go successfully. (They take long time to complete!)

npm run bootstrapThoughts:
I solved the error in npm run bootstrap but now I'm facing another error in the next step npm run seed. The same error has been filed as an issue in freeCodeCamp's GitHub repo recently so I might wait a few days to see how it goes. I will work on something else while waiting for it.
I solved the error in npm run bootstrap by globally installing opencollective beforehand by npm install -g opencollective

freeCodeCamp の Regular Expressions に関するレッスンのメモ。 Regular Expressions | freeCodeCamp
.test() メソッド: regex.test(テストしたいString); の形でチェックできる
let testStr = "somethingToTest";
let testRegex = /Test/;
testRegex.test(testStr);
// Returns true
.match() メソッド: string.match(regex); でマッチしたStringを取り出す
/freecodecamp/i の i の部分をflagという/freecodecamp/gi みたいに複数書ける.: wildcard character 何にでもマッチする[aiu]: a, i, u のどれにでもマッチする[a-z]: a から z の範囲の文字にマッチする[a-z0-9]: a-zと0-9の全て[^aeiou]: a, e, i, o, u 以外の 文字にマッチする
[] が示すのが character set だからかな？そこに記号は含まれてない？[^something] は、character set からsomethingを除外する[] の外で ^ が使われたときは意味が変わる。[] の外の ^ →Stringの最初でだけマッチする\w: [A-Za-z0-9_] と同じ(全てのアルファベット大文字小文字、数字、とアンダーバー) (＝"alphanumeric characters" というのはこれっぽい？)\W: 上の逆。 [^A-Za-z0-9_]\d: [0-9]\D: 上の逆。 [^0-9]a+: aが1回以上続けて出てくるa*: aが0回位以上続けて出てくる(下の例の /t[a-z]*?i/ で"ti"にマッチさせるときに効果を発揮する)? でlazy match(一番短いものにマッチする)にできる
let text = "titanic";
text.match(/t[a-z]*i/); // ["titani"]
text.match(/t[a-z]*?i/); // ["ti"]
