How to fix the string replace method not replacing text containing literal \r\n strings in JavaScript?
To fix the string replace method not replacing text containing literal \r\n strings in JavaScript, we can call replace with a regex to match all instances of \r\n and replace them with the characters we want.
For instance, we write:
const value = 'abc\r\ndef'
const newVal = value.replace(/(?:\\[rn]|[\r\n])/g, "");
console.log(newVal)
to call value.replace to replace all instances of \r\n with empty strings.
We use the /(?:\\[rn]|[\r\n])/g regex to find all instances of \r\n in value.
As a result, newVal is "abcdef".
