Remove characters from a string

Question

What are the different ways I can remove characters from a string in JavaScript

User · Answer

Another method that no one has talked about so far is the substr method to produce strings out of another string   this is useful if your string has defined length and the characters your removing are on either end of the string   or within some  static dimension  of the string

I know this is old but if you do a split then join it will remove all occurrences of a particular character ie   var str   theText split  A   join       will remove all occurrences of  A  from the string  obviously it s not case sensitive

Using replace   with regular expressions is the most flexible powerful   It s also the only way to globally replace every instance of a search pattern in JavaScript   The non-regex variant of replace   will only replace the first instance   For example   var str    foo gar gaz       returns   foo bar gaz  str replace  g    b        returns   foo bar baz  str   str replace  g gi   b      In the latter example  the trailing  gi indicates case-insensitivity and global replacement  meaning that not just the first instance should be replaced   which is what you typically want when you re replacing in strings   To remove characters  use an empty string as the replacement   var str    foo bar baz       returns   foo r z  str replace  ba gi
