What is the best way to eliminate two identical characters along with any content in between using JavaScript?

I am trying to figure out how to remove a specific part of a string that is between matching '/' characters. For instance:

'/this is/ a sentence' => ' a sentence'

Although I have limited experience with regex, I am wondering if it can be used to achieve this task or if there is an alternative method.

I understand that substring can be used for this purpose, but I am curious about the potential use of regex.

Currently, my approach is as follows:

const string = '/this is/ a sentence';
const substring = string.substring(4);

While this solution works, I am interested in exploring the capabilities of regex in this scenario.

Answer №1

Is it as simple as using the regular expression \/[^\/]*\/ and then replacing it with nothing?

var sentence = '/this is/ a sentence'
console.log(sentence + ' --> ' + sentence.replace(/\/[^\/]*\//g, ''))

The \/[^\/]*\/ regex pattern matches a forward slash followed by any character that is not a forward slash zero or more times, and then another forward slash. This matched portion is then replaced with an empty string.

Answer №2

To find a pattern in a string, you can use the regex \/.*?\/

  • \/ - This matches the forward slash character
  • .*? - This will match any character except for a new line in lazy mode

let str = '/this is/ a sentence'

let op = str.replace(/\/.*?\//g,'')

console.log(op)

Answer №3

Utilizing the following regular expression:

var sentence = "'/this is/ a phrase' => ' a phrase'";
var regex = sentence.replace(/(?!<\")\/[^\*]+\/(?!\")/g,'')
console.log("resulting string: " + regex);
