Using RegEXP in Javascript, you can easily eliminate characters that fall between two special characters without removing the special characters

I'm facing an issue with a string that looks like this:

var str = "1111 type reallycoolsentence\text.json\n1111 type anotherreallycoolsentence text2.json

My goal is to eliminate the characters located between the backslashes in the string.

This is the desired outcome I am seeking:

str = "type reallycoolsentence\\type anotherreallycoolsentence"

I do have knowledge on removing characters within special characters without altering the special characters themselves. Unfortunately, I couldn't find sufficient answers to my specific problem on various online platforms.

Answer №1

Make sure to include the backslashes in the replacement string.

Remember to double them to ensure they are treated as literal backslashes, as the backslash is an escape character in string literals.

var s = "1111 type reallycoolsentence\\text.json\\n1111 type anotherreallycoolsentence text2.json";
var result = s.replace(/\\.*\\/, '\\\\');
console.log(result);

The outcome may not match the example you provided, but it aligns with your specified requirements. I followed your instructions accurately.

Answer №2

For those who prefer alternatives to regular expressions:

  sentence = "1111 type reallycoolsentence text.json\n1111 type anotherreallycoolsentence text2.json"
  wordArray = sentence.split(" ");  
  wordArray = wordArray.filter( value => value !== "1111");
  wordArray = wordArray.filter(value => !value.includes('.json'));
  outputResult = wordArray.join(" ");

Output:

type reallycoolsentence type anotherreallycoolsentence
