JavaScript Language Intensive Guide 🔥

I wanted to create a course that you don't need to take any other courses after taking it once. Many people feel like something is lacking when they jump into practice after taking a basic course as a beginner, right? In order to relieve you of the trouble of searching for advanced courses and content to quench your thirst, I planned and completed a course that delves into everything from 🍼 the basics for beginners to 🍺 advanced concepts and applications for practitioners, after a long period of preparation.

This course is a deep dive into the JavaScript language, and the application of web development is covered only in the last section. Please check the curriculum before taking the course.

From basic to advanced
Grammar and functions in detail

Object-oriented, functional programming

Frequently Asked Questions
Check it out 💬

Q. What can I do if I learn JavaScript?

A. The uses of JavaScript today are endless. As a front-end developer, you can not only create websites, but also build Node.js-based servers. You can also create mobile apps or desktop programs, and you can use it for machine learning.

Q. I'm new to programming. Can I still take the class?

A. We planned and produced the lecture so that even those who are new to coding can follow along. We use easy terms so that even non-majors can understand without difficulty, and we explain the operating principles of the code in detail for those who have no programming experience. Since we utilize the browser console, you can take the lecture without a complicated installation process, and you can use the lecture page as a supplementary teaching material to follow the practice calmly. However, depending on the student, the progress may feel very fast , so if this is your first time taking Yalco's lecture , be sure to check out the free part in advance.

Q. I am already working with JavaScript. How helpful will this course be?

A. You can develop with just a 'moderate' knowledge of JavaScript, but if you have not studied it 'properly' and deeply, there is a limit to how much you can put the characteristics and strengths of this language into practice. If you take this course that delves into JavaScript, you will learn how to use JavaScript 'like JavaScript', and you will also learn how to analyze the functions you have used and utilize them more effectively. You will also be able to break free from the vagueness of what you know and don't know about JavaScript, and gain the confidence that you can do anything with this language.

Q. Will taking this course help me learn web development?

A. This course is designed to delve deeply into the grammar, theoretical knowledge, and advanced usage of the language itself called JavaScript. In the last section of the 16, you will learn about DOM and practice using it on websites in conjunction with HTML and CSS, but it mainly covers the core parts and analyzes them in depth from the perspective of JavaScript. If there is an opportunity, I will create a separate web development course that will fully practice front-end development.

Q. Is knowledge of HTML and CSS necessary or helpful?

A. (Linked to the question above) Since the part about using JavaScript on web pages only appears in the last section, you can take the lecture without any knowledge of HTML and CSS in the previous 15 sections. If you have basic knowledge, you can take Section 16 without much difficulty.

Q. The lectures are fast paced, so won’t they be difficult?

A. The video progresses quickly, but each lecture has a linked lecture page so that you can easily review and practice the video content. You will be able to learn in a way that maximizes your time efficiency by utilizing examples throughout the page and the browser console!

    ブラウザコンソールを活用してJavaScriptを研究、分析するように学んでいく過程がとても楽しかったです。これまでjsを適当にだけ知ってリアクトランノードを使ってきたが、この講義を聞きながら、ああ、これはこういう原理だったんだと悟ったのが本当に多かったです。ヤルコ様らしい簡単な説明のおかげで、高度な概念も簡単に学ぶことができました。 Jsを講義のタイトルのようにきちんと掘り下げて勉強してみたい方には本当に楽しい講義になりそうです。現業でjsを使う方に特に強力おすすめです。

    これまで講義評 一度も残したことがないのにこれは本当に..ㅋㅋㅋㅋㅋㅋㅋㅋㅋ 非専攻者なのですが、この講義でJavaScriptを始めることになり、誠に幸いです。後で他の言語を勉強するときにも役に立つと思います。メモリアドレス扱ってくださるのを見て感動しました。 。以前にC++を少し勉強したとき、メモリ部分でヒープ、スタックがとても混乱していましたが、もう少し整理になりますね。 。とても面白いです。 実はヤルパクなコーディング辞典というニックネームのために軽く心配しながらも内容が軽くて早く済ませられるという考えで決済しましたが途方もない反転ですね。 これは本当にその分野を深く理解している人だけが撮れる講義だと思います。これまで私が勉強した基本文法はあまりにも軽さそのものだったことに気づきました。次に準備しておられる講義は何ですか..本当に期待されますね..

    9講まで聞いて中評残します。 このレッスンは、プログラミング入門者のためのプログラミング言語レッスンではなく、 他の言語を少なくとも入門段階までは終えた人を対象とする講義で感じられます。 ゆっくりとプログラミングの味を見せるというよりは、JavaScript言語自体に対して掘り下げる感じです。 講義が難しく感じられる方はあまり無理に覚えようとしないで、簡単な問題プールや作品開発をしながら'コーディングちゃん'を満たしてからまた戻ってもいいようです。 (もちろん無料講義パートがご理解のあった方はおびえずに決済してもいいと思います) 私はJavaの経験がある程度あると聞いたので理解するのは難しくありませんでした。 開発経験が全くない状態で聞いたら理解できない内容がほとんどだったようです。 そして、インストラクターがコードを見ながら、このような結果は、次のようになります。のような指示代名詞を多く使用しますが、 受講者が川の流れに完全に追いつくと同時に講師のマウスカーソルの動きを集中していない以上 'これ'が何を言っているのかを理解するのは難しいので、指示代名詞の使用をわざわざ避けることは講義の理解に良いと思います。 ex) toString 関数をこうして実行したところ、このような結果が出ましたね。 ex) toString関数引数として2を入れて実行したところ、0b11という文字列が出ました - O 受講評が酷評のように聞こえますが、私はとても満足して聞いています。 サンプルコードと結果値をすばやく確認し、結果を分析する講義の流れのおかげで 伸びないように短い分量に多くの情報を盛り込んで、 入門者が理解しにくい説明があると思われますが、それが説明が不親切であるという話ではありません。 どの程度のプログラミング経験がある人がJavaScriptという言語がどんな言語なのか知りたいのなら、定価5万どのくらいにこの程度によく圧縮され、よく準備された講義を購入することは非常に良い判断と考えられます。 *発音の話がありましたが、発音が変なのは一度も感じられませんでした。 ヤルコ様のYouTubeとインフラの川の両方をよく見ています。

      [2023/11/1 追加回答です。] 申し上げた内容を反映し、講義を全般的に再編集しました。 画面切り替えなどが早すぎる部分に少し余裕を与えて体感速度を下げました。 ビデオで話す部分を画面上で見つけやすいようにマーカーを追加しました。 時間がとても長くかかる作業だった点ご了承ください。 今再び映像を見れば、以前よりずっと受講する方が良いでしょう。 貴重なフィードバックをいただき、講義を向上させていただきありがとうございます。 良いフィードバックのおかげで講義を全体的に改善することになりました。もう一度ありがとう! - - - - - 詳細で思いやりのある講義評に感謝!おかげで、未だ思っていなかった点を確認することができ、どんな部分をより具体的に改善すべきか、入門者の方々をどのようにさらに配慮できるかについてもっと考えてみることができました。 教えてくれた部分を次の講義に最大限反映して、より良いコンテンツを作ってみたいと思います。 講義がパク・ジョンシクに助けてくれて本当に幸いで嬉しいです。受講していただきありがとうございます!

    初めて開講した時数日見て会社日の言い訳で釘よりが最近また見ています! 従来は本でどんどん見た内容であり、しっかり理解がうまくいかなかったのですが、基本から上級概念まで本当に簡単によく説明してくれます。 どんなフレームワークを使っても、jsの基本は基礎になるべきだと思いますが、基本を着実に固めるのにとても素晴らしい講義です! 頑張った後も混乱したら探してみながら繰り返し受講しなければなりそうです〜!

    'バックエンド'を目指し、'フロント'は単に機能の実装だけに目を引いた先日を反省するようになりました。 基礎から深化内容まで頑張ってみるとこんなに面白い言語だったことがわかりました。 もう一度振り返って繰り返し学習しなければならないようで(ちゃんと面白く知りたくて)もう少し可愛いコードを作らなければならないと思います!良い講義でした。 ありがとうございます。
