I have also written some other languages, such as <code>JavaScript</code>, <code>Dart</code>, etc.</p> <p>This website was established to record my thoughts, because I find that in-depth study is very necessary. Unfortunately, the past few years of my coding career have not been carefully documented, so much knowledge and thinking has been lost.</p> <p>Thanks for reading.</p>
