js hive 语法解析
    英文回答：
    JS and Hive are two different programming languages used for different purposes.
    JS, short for JavaScript, is a scripting language primarily used for web development. It is a high-level, interpreted programming language that allows you to add interactivity and dynamic behavior to websites. With JS, you can manipulate HTML elements, handle events, create animations, and perform various tasks on the client-side.
    On the other hand, Hive is a data warehouse infrastructure built on top of Hadoop. It provides a SQL-like language called HiveQL, which allows you to query and analyze large datasets stored in Hadoop Distributed File System (HDFS). HiveQL is similar to SQL, but it is specifically designed for working with big data. Hive translates the HiveQL queries into MapReduce jobs, which are then executed on the Hadoop cluster.
    Let me give you an example to illustrate the difference between JS and Hive. Suppose you
have a website that displays a list of products and you want to add a feature that allows users to filter the products based on their price range. In this case, you would use JS to handle the user interaction and dynamically update the product list based on the selected price range.
    Here's how you could achieve this using JS:
    javascript.
    // HTML.
    <input type="range" id="priceRange" min="0" max="100" step="10">。
    <ul id="productList">。
      <li data-price="20">Product A</li>。
      <li data-price="50">Product B</li>。
      <li data-price="80">Product C</li>。
    </ul>。
    // JS.
    const priceRange = ElementById('priceRange');
    const productList = ElementById('productList');
    priceRange.addEventListener('input', () => {。
      const selectedPrice = priceRange.value;
jsarray删除元素      Array.from(productList.children).forEach((product) => {。
        const price = product.dataset.price;
        if (price <= selectedPrice) {。
          product.style.display = 'block';
        } else {。
          product.style.display = 'none';
        }。
      });
    });
    In this example, the JS code listens to the input event of the price range slider and updates the visibility of the products based on the selected price range.
    Now, let's consider a scenario where you have a large dataset of customer transactions stored in HDFS, and you want to find the total sales amount for each customer. In this case, you would use HiveQL to query the data and perform the aggregation.
    Here's an example HiveQL query:
