How to make a regular?

Question

JavaScript

It is necessary to remove these characters #&|?:"" from the string . I do not understand how to make it so that characters are deleted individually from different places in the string. At me it turns out to delete them only by a line.

Answer 1

str.replace(/[#&|?:«»]/g, '')

Answer 2

in order to have an enumeration, for example from and to, square brackets are used. by analogy /[0-9]/ will mean that each digit from 0 to 9 falls into the sample. The same with letters /[0-9a-z]/. add "i" to this regular expression and get a case-insensitive sample - /[0-9a-z]/i
