Check [pitfalls] in the regular expressions in javascript and brackets in the regular expressions.
When using regular expressions in javascript, you need to pay attention to a pitfall in brackets, that is, the metacharacters in brackets. I stepped on the trap myself. I searched the internet and many others stepped on the trap, so I 'd like to explain it.
Let us define a regular brackets sequence in the following by:1. Empty sequence is a regular sequence.2. If S is a regular sequence, then (s) and [s] are both regular sequences.3. If A and B are regular sequences, then AB is A regular sequence.For example, all of the following sequences of characters is regular brackets sequences:(), [], (()), ([]), ()[], ()[()]And all of the following character sequences i
