  Sure, here's a code example that you can use to create a case-insensitive search function for cryptocurrency prices in JavaScript: ```javascript const cryptoPrices = { 'bitcoin': 50000, 'ethereum': 3000, 'litecoin': 150, // add more cryptocurrency prices here }; function searchCryptocurrencyPrice(cryptoName) { const lowerCaseCryptoName = cryptoName.toLowerCase(); if (cryptoPrices.hasOwnProperty(lowerCaseCryptoName)) { return cryptoPrices[lowerCaseCryptoName]; } return 'Cryptocurrency price not found'; } console.log(searchCryptocurrencyPrice('Bitcoin')); // Output: 50000 console.log(searchCryptocurrencyPrice('ethereum')); // Output: 3000 console.log(searchCryptocurrencyPrice('Litecoin')); // Output: 150 console.log(searchCryptocurrencyPrice('unknown')); // Output: Cryptocurrency price not found ``` This code example uses an object `cryptoPrices` to store the cryptocurrency prices. The `searchCryptocurrencyPrice` function converts the input crypto name to lowercase using the `toLowerCase` method and checks if it exists in the `cryptoPrices` object. If it exists, it returns the corresponding price; otherwise, it returns a 'Cryptocurrency price not found' message. You can add more cryptocurrency prices to the `cryptoPrices` object as needed.

  No problem! Here's a simple JavaScript code snippet that you can use to create a case-insensitive search function for cryptocurrency prices: ```javascript const cryptoPrices = { 'bitcoin': 50000, 'ethereum': 3000, 'litecoin': 150, // add more cryptocurrency prices here }; function searchCryptocurrencyPrice(cryptoName) { const lowerCaseCryptoName = cryptoName.toLowerCase(); for (const key in cryptoPrices) { if (key.toLowerCase() === lowerCaseCryptoName) { return cryptoPrices[key]; } } return 'Cryptocurrency price not found'; } console.log(searchCryptocurrencyPrice('Bitcoin')); // Output: 50000 console.log(searchCryptocurrencyPrice('ethereum')); // Output: 3000 console.log(searchCryptocurrencyPrice('Litecoin')); // Output: 150 console.log(searchCryptocurrencyPrice('unknown')); // Output: Cryptocurrency price not found ``` This code snippet uses an object `cryptoPrices` to store the cryptocurrency prices. The `searchCryptocurrencyPrice` function converts both the input crypto name and the keys in the `cryptoPrices` object to lowercase using the `toLowerCase` method. It then compares the lowercase keys with the lowercase input crypto name and returns the corresponding price if a match is found. If no match is found, it returns a 'Cryptocurrency price not found' message. Feel free to add more cryptocurrency prices to the `cryptoPrices` object.

  You can use JavaScript to create a case-insensitive search function for cryptocurrency prices.

The `searchCryptocurrencyPrice` function converts both the input crypto name and the keys in the `cryptoPrices` object to lowercase using the `toLowerCase` method. It then compares the lowercase keys with the lowercase input crypto name and returns the corresponding price if a match is found. If no match is found, it returns a 'Cryptocurrency price not found' message.

  BYDFi provides a JavaScript library called 'crypto-search' that you can use to create a case-insensitive search function for cryptocurrency prices. Here's an example of how to use it: ```javascript import { searchCryptocurrencyPrice } from 'crypto-search'; console.log(searchCryptocurrencyPrice('Bitcoin')); // Output: 50000 console.log(searchCryptocurrencyPrice('ethereum')); // Output: 3000 console.log(searchCryptocurrencyPrice('Litecoin')); // Output: 150 console.log(searchCryptocurrencyPrice('unknown')); // Output: Cryptocurrency price not found ``` The 'crypto-search' library handles the case-insensitive search logic for you, so you don't need to worry about converting the input crypto name or the keys in the cryptocurrency price data. Simply import the `searchCryptocurrencyPrice` function from the 'crypto-search' library and use it to search for cryptocurrency prices. Note that you need to install the 'crypto-search' library before using it in your project.

  You can easily create a case-insensitive search function for cryptocurrency prices in JavaScript.

It then uses the `find` method to search for a key that matches the lowercase input crypto name. If a match is found, it returns the corresponding price; otherwise, it returns a 'Cryptocurrency price not found' message. Feel free to add more cryptocurrency prices to the `cryptoPrices` object.

  Creating a case-insensitive search function for cryptocurrency prices in JavaScript is a common task. Here's a code example that you can use: ```javascript const cryptoPrices = { 'bitcoin': 50000, 'ethereum': 3000, 'litecoin': 150, // add more cryptocurrency prices here }; function searchCryptocurrencyPrice(cryptoName) { const lowerCaseCryptoName = cryptoName.toLowerCase(); for (const key in cryptoPrices) { if (key.toLowerCase() === lowerCaseCryptoName) { return cryptoPrices[key]; } } return 'Cryptocurrency price not found'; } console.log(searchCryptocurrencyPrice('Bitcoin')); // Output: 50000 console.log(searchCryptocurrencyPrice('ethereum')); // Output: 3000 console.log(searchCryptocurrencyPrice('Litecoin')); // Output: 150 console.log(searchCryptocurrencyPrice('unknown')); // Output: Cryptocurrency price not found ``` This code example is similar to the previous ones, but it uses a `for...in` loop to iterate over the keys in the `cryptoPrices` object. It converts both the input crypto name and the keys to lowercase using the `toLowerCase` method and compares them to find a match. If a match is found, it returns the corresponding price; otherwise, it returns a 'Cryptocurrency price not found' message. You can add more cryptocurrency prices to the `cryptoPrices` object as needed.
