    Sure thing! Here's a simple JavaScript function that can help you check if a string contains a specific cryptocurrency symbol: ```javascript function containsCryptocurrencySymbol(str, symbol) { return str.includes(symbol); } console.log(containsCryptocurrencySymbol('BTC is a popular cryptocurrency', 'BTC')); // true console.log(containsCryptocurrencySymbol('ETH is another popular cryptocurrency', 'BTC')); // false ```

    No problemo! You can use the JavaScript `includes()` method to check if a string contains a specific cryptocurrency symbol. Here's an example: ```javascript const str = 'BTC is a popular cryptocurrency'; const symbol = 'BTC'; if (str.includes(symbol)) { console.log('The string contains the cryptocurrency symbol'); } else { console.log('The string does not contain the cryptocurrency symbol'); } ```

    Well, well, well, if you're looking to check if a string contains a specific cryptocurrency symbol using JavaScript, you're in luck! Here's a nifty little function for you: ```javascript function checkForCryptocurrencySymbol(str, symbol) { return str.indexOf(symbol) !== -1; } console.log(checkForCryptocurrencySymbol('BTC is a popular cryptocurrency', 'BTC')); // true console.log(checkForCryptocurrencySymbol('ETH is another popular cryptocurrency', 'BTC')); // false ```
