JavaScript Replace – How to Replace a String or Substring in JS
November 7, 2024 - In this example above, the regular expression /\D/g matches all non-digit characters in the originalString. The \D character class matches any character that is not a digit. The g flag specifies that all matches should be replaced. Regular expressions make it possible for you to perform advanced search and replace operations. For example, using the i flag, you can replace only strings and substrings whose case matches perfectly: const originalString = "I love JavaScript and javascript loves me"; const newString = originalString.replace(/JavaScript/i, "Python"); console.log(newString); // Output: "I love Python and javascript loves me"

March 16, 2015time complexity of javascript functions
Any toString method where the returned string contains the object's contents in some form obviously can't be O(1) (you can't create a string containing n items in less than O(n) time). A toString method that just returns a fixed string (like Object.prototype.toString, which just returns "[object Object]") would be O(1) though. String.prototype.replace has to at least be O(n) because it has to search through the entire string in the worst place and because it has to create a new string whose length will linear in the length of the original string. And creating a string of length n is of course an O(n) operation. But with a sufficiently complicated regex, the complexity can actually be much worse than O(n) - the complexity of matching regular expressions, as implemented in JavaScript and many other languages at least, can be exponential in pathological cases.
