Sometimes, we come across a requirement where we need to find the substrings in a paragraph. We will achieve this by using both, JavaScript and jQuery. JavaScript provides a RegExp class to create a regular expression based on your variables: const search = '-`Ĭonst string = 'e851e2fa-4f00-4609-9dd2-9b3794c59619'Ĭonsole.log(string.In this article, we will learn how to search and locate the words or substrings in paragraphs or large strings. You should create a RegEx when using dynamic values as the search string. A regular expression with the /g suffix replaces all dashes with an empty string. Pass it in as the first argument to string.replace(): const string = 'e851e2fa-4f00-4609-9dd2-9b3794c59619'Īs you can see, using a string as the substring to search for will only replace the first appearance. String.replace(): Replace All AppearancesĪ regular expression instead of a string will replace all appearances. The next section describes you how to replace all dash appearances in the string. It won’t replace the second, third, and other dashes in the string. The problem: it replaces only the first dash because the method searches for the substring“-” and stops when found. Now you may go ahead and use string.replace('-', ''). A way to go is replacing all dashes with an empty string. Now you want to remove all dashes in this string. Imagine the following example: you have a string that includes dashes, like a UUID.
