1. Grasp The Basics More Thoroughly
Even two small periods or quotation marks can be the cause. These things happen due to unclear basic concepts. A simple loop like for or do while is used multiple times in a single program. Loops are fundamental elements in programming. If you don’t know about loops and other basics, it will be very difficult for you to write code and even have a chance to get hired by a company. Improving the basics is very important because it provides a solid foundation for building the complex logic of a solution and a good reputation.
2. Use Functions To Define Different Modules, Even If They Are Small
A functional approach is a great approach to programming. Why? Divide your program into modules that work together but are separate. I would like to use an example to clarify. There is a function to calculate the mean square of numbers. To do this, you need to square the numbers, calculate their mean, and calculate the square root of the mean. This involves three steps. So we can use three functions. But you see, all these functions are interconnected.
3. Keep Cross Browser Compatibility In Mind
However, this is no longer the case as online browser compatibility testing tools like LambdaTest have eliminated this problem. All you have to do is enter your site name and select the versions, browsers (and operating systems) you want to test your site on. This creates a virtual machine on the LambdaTest servers and you are ready to go. You will receive a detailed report with screenshots and can also run your website as if it were running in the browser.
4. Use Object-Oriented Approach
The object-oriented approach is the most popular programming approach today. Since C++, the object-oriented approach has enjoyed exponential popularity. All major languages today were invented exclusively in object-oriented style. An object-oriented approach is called an object-oriented approach. This is how an object becomes a basic unit. This object is then used as a base and to apply properties and functions to the page.
For example, I create a car object. This item can be packaged in various features such as color, specifications, price, etc. and everything we do is in this object. We can choose a car. Color (“Red”) to change the color of the car to red. We can also change the price per car. Price (“50”). An object is the basis of everything you do in the programming language. Now it is no longer important to create an object and use it. They are used with an object-oriented approach, but it is also possible to take the traditional approach by simply writing top-down code without functions or objects. This is too broad and is never recommended.
5. Perform Testing To Have A Near Perfect Code
6. Error Handling
If you like to code, your code is prone to errors. When working on a large project, mistakes are often common. And they should be. They open up more possibilities that you might not have thought of while coding. However, these errors must be handled properly or else they will interrupt program flow. Now, console.log is a traditional method for logging errors. However, they are long and verbose. To handle errors more efficiently, you can use error objects. An error object looks like this:
const err = new Error(‘Please improve the time complexity of the code’)
console.log(err.message) // please improve your code
This will also allow you to see an error message. You can also use try, catch and finally to apply validations to your code. If an error is detected in the code of the Try block, you can access the Catch block to execute an error code or display a message. Finally, Block executes the code in all cases whether there is an error or not. Here is some sample code:
catch (Exception e)
