JavaScript RegExp Group [^abc]

Do a global search for characters NOT inside the brackets [h]:

let text = "Is this all there is?";
let pattern = /[^h]/g;

Description

Brackets [^abc] specifies matches for any character NOT between the brackets.

Brackets can define single characters, groups, or character spans:

[^abc]	Not any of the characters a, b, or c
[^A-Z]	Not any character from uppercase A to uppercase Z
[^a-z]	Not any character from lowercase a to lowercase z
[^A-z]	Not any character from uppercase A to lowercase z

/[^abc]/ is an ECMAScript1 (ES1) feature.

ES1 (JavaScript 1997) is fully supported in all browsers:


Chrome	Edge	Firefox	Safari	Opera	IE
Yes	Yes	Yes	Yes	Yes	Yes

new RegExp("[^ xyz]")

or simply:

/[^ xyz]/

new RegExp("[^ xyz]", "g")

or simply:

/[^ xyz]/g

Use the [abc] expression to find any character BETWEEN the brackets.

Do a global search for characters that are NOT "i" and "s" in a string:

let text = "Do you know if this is all there is?";
let pattern = /[^is]/gi;

Do a global search for the character-span NOT from lowercase "a" to lowercase "h" in a string:

let text = "Is this all there is?";
let pattern = /[^a-h]/g;

Do a global search for the character-span NOT from uppercase "A" to uppercase "E":

let text = "I SCREAM FOR ICE CREAM!";
let pattern = /[^A-E]/g;

Do a global search for the character-span NOT from uppercase "A" to lowercase "e":

let text = "I Scream For Ice Cream, is that OK?!";
let pattern = /[^A-e]/g;

Tip: Use the [abc] expression to find any character between the brackets.

Do a global, case-insensitive search for the character-span that's NOT [a-s]:

let text = "I Scream For Ice Cream, is that OK?!";
let pattern = /[^a-s]/gi;

In JavaScript, a regular expression text search, can be done with different methods.
