Javascript - case insensitive replace when the text you want to replace contains forward slashes?

Question

I am trying to do a case insensitive replace based on a URL where I need to include forward slashes in the text to be replaced. I know that you can remove case sensitivity like this:

str.replace(/lorem/gi, 'ipsum');

But how would I do that if the text to replace contained a forward slash such as this:

str = 'http://example.com/lorem/ipsum.txt';

and I want to replace /lorem/ with /ipsum/

Answer 1

You just have to escape the forward slashes. The character for that is the backslash \

let str = 'http://example.com/lorem/ipsum.txt';
let final = str.replace(/\/lorem\//gi, '/ipsum/');

console.log(final);
