This will produce the same result as the previous example, replacing all occurrences of "replace" with "substitute". Let newString = originalString.replaceAll("replace", "substitute") let originalString = "Replace me, replace me!" Starting from Node.js version 15.0.0, the String.replaceAll() method was introduced, providing a convenient way to replace all occurrences of a substring without using regular expressions. String.replaceAll() Method (Node.js 15.0.0 and later) The output will be "Substitute me, substitute me!" as the global flag ensures that all occurrences of "replace" are replaced. Let newString = originalString.replace(/replace/g, "substitute") If you want to replace all occurrences of a substring, you can use the global flag ( g) with a regular expression. Global Replacement with Regular Expressions Here, the output will be "Node.js is powerful!" as the regular expression is used to match the word "awesome" and replace it with "powerful". Let newString = originalString.replace(/awesome/, "powerful") ![]() let originalString = "Node.js is awesome!" The String.replace() method can also take a regular expression as its first argument, allowing for more flexible replacements. Node.js supports regular expressions for advanced string manipulation. In this example, the output will be "Hello, Node.js!" as the method replaces the first occurrence of "World" with "Node.js". Let newString = originalString.replace("World", "Node.js") This method takes two arguments: the substring you want to replace and the new substring you want to insert. The most straightforward way to replace a string in Node.js is by using the String.replace() method. ![]() How to Replace String in Node.js String.replace() Method In this article, we'll explore different ways to replace strings in Node.js and understand the various methods available for this task. Whether you're working with data processing, text parsing, or building a web server, the ability to replace strings is a fundamental skill. Node.js has become a popular platform for server-side development, and manipulating strings is a common task in many applications.
