Do I use .size() or .length in Javascript?
Article Introduction：Use .size() or .length() in JavaScript?
Let's take a closer look....size() actually just calls .length (which is clearly shown by the jQuery source code shown below), so we save a function call:
//https://code.jquery.com/jquery-latest.js
// The number of elements contained in the matching element set
size: function() {
return this.length;
},
Tests have proven that .length() is more speedy than .size()

Sublime automatically wraps
Article Introduction：Sublime Text's automatic line wrapping feature significantly improves coding efficiency, but needs to be used with caution. 1. Advantages: Improve the readability of long code, reduce scrolling, and improve efficiency; 2. Disadvantages: Copy and paste may lose line breaks, and the line number may not match the debugger during debugging. Therefore, it is recommended to cancel the automatic wrap before copying or manually adjust the format after copying. Automatic wrapping should also be temporarily turned off during debugging. Only by rationally setting the line break width and combining other functions can it maximize its effectiveness and avoid potential problems.

How to use bookmarks in the SQL editor?
Article Introduction：Bookmarks are used in SQL editor to quickly jump code positions to improve efficiency. When you write complex queries or frequently switch code segments, bookmarks can be positioned with one click to avoid scrolling searches. Common operations are as follows: DBeaver uses Ctrl F11 to add and F11 to jump; DataGrip/IDEA uses F11 to add unnumbered bookmarks, Ctrl Shift numbers set the number and jump; VSCode installs the plug-in with Ctrl Alt K and Ctrl Alt J to jump. It is recommended to name the bookmark, use it in combination with numbering, and clean invalid bookmarks regularly. If the editor does not support native bookmarks, you can install the plug-in extension function. Use bookmarks reasonably in just a few minutes to learn, but can significantly improve daily SQL development
