If you want to show your project experience in your resume, be sure to have highlights. An example of an exported Excel file that is too large and causes the browser to freeze is a good highlight. You can include this example in your resume. If the interviewer asks, you can use the principle of the browser to explain. The browser kernel can be simply divided into the following five threads: GUI rendering thread, JS engine thread, event trigger thread, timing trigger thread and asynchronous HTTP request thread. The GUI rendering thread and the JS engine thread work together. If the JS engine thread does a lot of calculations, even if the GUI thread has an update, it will remain in the queue, waiting for the JS engine to be idle. If you export an Excel with 100,000 entries, the JS engine will do a lot of calculations, which may cause it to idle for a long time, causing the browser to freeze.
To solve this problem, Web Workers can be used. This passage is the official explanation of MDN. Web Worker can be understood in this simple way: when creating a Web Worker, the JS engine applies to the browser to open a sub-thread, and the JS engine thread communicates with the Web Worker thread in a specific way, generally using the postMessage method. If you have very time-consuming work, you can open a Web Worker separately. Changes inside the Web Worker will not affect the rendering of the JS engine, just wait for the Web Worker to calculate the result and notify the main thread of the result.
When using Web Worker, you need to pay attention to the following 5 points, and also note that the JS engine is single-threaded. The nature of this is not going to change. In addition, in addition to Web Worker, there is a new technology called Service Worker, you can learn about it.
Regarding MATLAB programmer learning, you need to pay attention to the following points:
- Familiar with the syntax and basic operations of MATLAB language, including matrix operations, image processing, signal processing, etc.
- Learn the toolboxes of MATLAB, such as statistical toolboxes, control toolboxes, etc.
- Learn programming skills of MATLAB, such as function writing, object-oriented programming, etc.
- In the process of learning, you must continue to practice, do more experiments and projects, and improve your practical ability.
- Highlighting your professional skills and practical experience in the MATLAB field in your resume can impress recruiters.
MATLAB and PHP are both programming languages, but they have their own advantages and disadvantages.
One of the strengths of MATLAB is its ease of learning and quick use, which puts many beginners at ease. In addition, MATLAB is specially used for mathematical calculation and algorithm development, and has good mathematical and engineering calculation capabilities. It has a rich toolbox, which is convenient for users to carry out scientific computing and engineering design, and supports many scientific computing fields, such as signal processing, image processing and control systems. The speed of writing programs is fast, and the code is concise and easy to read, which makes it easier to write MATLAB code.
However, MATLAB also has disadvantages. The biggest problem is the high price, which is not very affordable for individual users. In addition, its application fields are limited, mainly in scientific computing and engineering design. Slow speed is also an issue when computing at scale and processing complex data.
PHP is an open source and free programming language for personal and business users. It has a low learning threshold and is easy to use. PHP is versatile and can be used for website development, server-side programming, and more. It supports a variety of databases, such as MySQL, Oracle and so on. PHP is relatively fast, which makes it a popular programming language.
However, PHP also has some disadvantages. First of all, it is not suitable for large-scale mathematical calculations and algorithm development. Secondly, the code structure is confusing and the readability is poor. Security issues are also prominent. Lack of strict programming specifications can easily lead to code confusion and inefficiency.
Overall, both MATLAB and PHP have their pros and cons. For different application scenarios, it is very important to choose a suitable programming language.
A MATLAB programmer is a class of developers who specialize in the MATLAB programming language. Due to the wide application of MATLAB in scientific computing, engineering design, finance and other fields, MATLAB programmers have broad development prospects in these fields.
