![]() We can make a regular array from it using om. Esta sintaxis sirve como patrn donde cualquier parte de la cadena que coincida con ella ser reemplazada por la nueva sub cadena. There are 3 differences from match: It returns an iterable object with matches instead of an array. Para usar RegEx, el primer argumento de replace se reemplazar con la sintaxis de expresiones regulares, por ejemplo / regex /. It’s used mainly to search for all matches with all groups. If you want to change the value of the sentence variable to contain no white spaces, you need to assign it to a new variable, and then reference that variable from now on when you need access to it. The method str.matchAll (regexp) is a newer, improved variant of str.match. Note: we haven’t modified the original sentence variable by doing this, we’re just using console.log() to print out how it would look if you use the replace(/\s/g, "") regex method on it. Finally, what are we replacing the white space with what? Any empty string "" which is what removes the white space characters and makes every word glued into a single word. Heres an example: // matches a number, some characters and another number const reg /d.d/ const str 'Java3foobar4Script' const newStr str.replace(reg, '-') console.log(newStr) // 'Java-Script'.This tells JavaScript to replace all matched values. This syntax serves as a pattern where any parts of the string that match it will be replaced with the new substring. If you don’t add the g, only the first white space instance (between This sentence) will be replaced. 2 Answers Sorted by: 42 Well, first youll need the g flag on the regex. To use RegEx, the first argument of replace will be replaced with regex syntax, for example /regex/. ![]() Then we use the global g flag, which tells JavaScript that we want to find all the white space characters from the string.Because backslash ( \) is a reserved escape character in JavaScript, we add / in front of it to unescape it, so it becomes /\s/. Then add the aforementioned \s meta character as an argument to find white space characters.The replace () method returns a new string with the value (s) replaced. In JavaScript, regular expressions are also objects. First, we attach the replace() method to the sentence variable that references the string that we want to remove white space from. Description The replace () method searches a string for a value or a regular expression. Regular expressions are patterns used to match character combinations in strings.replace ( / \s / g, "" ) ) // Thissentencehas6whitespacecharacters. Const sentence = "This sentence has 6 white space characters."Ĭonsole.
