In JavaScript, a forward slash serves multiple purposes such as division operator, string character, etc. In this article, we will see how to globally replace a forward slash in a JavaScript string.
Below are the methods used to globally replace a forward slash in a JavaScript string:
Method 1: Using replace() method with a regular expression.
- The
replace()
method searches a string for a specified value or expression, replacing it with a new value. The original string remains unchanged.
- To replace all forward slashes, a regular expression is used. The forward slash (/) is a special character in regex, necessitating escape with a backward slash ().
- The global modifier (g) in the regular expression ensures the replacement of all occurrences of forward slashes in the given string.
- Importantly, the
replace()
method does not modify the original string; it returns a new string with replacements.
Syntax:
originalString.replace(/\//g, replacementString);
Example: In this example, we are using the JavaScript replace() method.
Javascript
let origString = 'string / with some // slashes /' ;
console.log(origString);
let replacementString = '*' ;
let replacedString = origString.replace(/\
console.log(replacedString);
|
Output
string / with some // slashes /
string * with some ** slashes *
- The split() method breaks a string into parts using a chosen separator, such as the forward slash. This creates an array of strings based on where the slashes were.
- The join() method then combines an array of strings back into one. By specifying a new character as a parameter, it replaces all the original forward slashes in the initial string.
- Together, split() and join() offer a straightforward way to replace specific characters, like the forward slash, in a given string.
- It’s crucial to note that these operations don’t change the original string; instead, they produce a new string with the desired modifications.
Syntax:
origString.split('/').join(replacementString);
Example: In this example, we are using JavaScript split() method.
Javascript
let origString = 'string / with some // slashes /' ;
console.log(origString);
let replacementString = '*' ;
let replacedString =
origString.split( '/' ).join(replacementString);
console.log(replacedString);
|
Output
string / with some // slashes /
string * with some ** slashes *
The JavaScript replaceAll() method returns a new string after replacing all the matches of a string with a specified string or a regular expression. The original string is left unchanged after this operation.
Syntax:
const newString = originalString.replaceAll(regexp | substr , newSubstr | function);
Example: In this example, we are using JavaScript replaceAll() method.
Javascript
let origString = 'string / with some // slashes /' ;
console.log(origString);
let replacementString = '*' ;
let replacedString =
origString.replaceAll( '/' , '*' );
console.log(replacedString);
|
Output
string / with some // slashes /
string * with some ** slashes *
