Let's assume that we have the following string:
javascriptlet string = `Erik exclaimed, "I am a good developer. She responded, 'No, you are not'."`;
To replace both single and double quotation marks:
javascriptlet noQuotationString = string.replaceAll(`"`, ``).replaceAll(`'`, ``); // Erik exclaimed, I am a good developer. She responded, No, you are not.
