How can I handle null values in JavaScript?

I'm working on a JavaScript project and I often encounter null values. What are the best practices and techniques for handling null values in JavaScript? Are there any specific functions or libraries that can help with null value handling?

When it comes to handling null values in JavaScript, there are a few best practices and techniques you can follow. First, it's important to perform proper null value checks before accessing properties or invoking methods on variables. This can be done using conditional statements such as if or ternary operators. For example, you can check if a variable is null before accessing its properties like this: if (variable !== null) { // access properties }. This helps prevent null reference errors and ensures your code doesn't break when encountering null values.
