Replace any of several characters with underscore-CodePudding

I have a simple task but I'm not sure of the syntax.

I have a string and want to replace any occurrences of '[', ']', or '.' with an underscore ('_').

I know that string.replace() supports regular expressions, which also give special treatment to [ and ].

CodePudding user response：

Use replaceAll for that

** Note, replace will also work since this a global search.

const src = '/[[\].]/g';
const target = '_';

const formated = string.replaceAll(src, target);

CodePudding user response：

Escape the characters with special treatment with backslash.

string = string.replace(/[[\].]/g, '_');

Note that [ and . don't receive special treatment inside [].
