Article Introduction：Regular expressions are a powerful pattern matching tool in JavaScript. They define matching rules by using /pattern/ syntax, and can be used to verify or extract information in combination with .test() or .match() methods. For example, /hello/ is used to match "hello" in a string, while adding an i flag such as /hello/i achieves case-insensitive matching. Special characters such as ., *, etc. need to be escaped with backslashes to match the literal value. At the same time, shortcut symbols such as \d (number), \w (word characters), \s (blanks) can be used. The symbols g (global search), i (ignoring case), and m (multi-line mode) can enhance matching flexibility. The matching content can be grouped and captured by brackets ().
