Utilizing JavaScript regex to remove substrings that contain parentheses

I am working with a string variable named myString that includes some unwanted content towards the end:

var myString = 'The sentence is good up to here foo (bar1 bar2)';
var toBeRemoved = 'foo (bar1 bar2)';

I am looking for the best way to utilize JavaScript regex to remove the undesired portion. I have encountered an issue when using the replace() method due to the presence of parentheses.

Edit:

After taking Matthew's suggestion and attempting to escape the parentheses, it initially appeared unsuccessful. However, upon trying again, it worked as intended.

var myString = 'The sentence is good up to here foo (bar1 bar2)';
var toBeRemoved = 'foo (bar1 bar2)';
document.write(myString .replace(/foo \(bar1 bar2\)/i, ''));

Thank you, Matthew.

Answer №1

In order to properly handle parentheses in regular expressions, you must escape them using \( and \). For example:

myString.replace(/\w+\s+\(.*?\)/, "")
