If you want to eat by writing programs, you must have a few

Javascript

Among these technologies, JavaScript is the first, and 42.4% of job vacancies require this skill. Why is JavaScript so powerful? The main reason is the prevalence of network software development. Javascript is the basis of many existing development frameworks. In addition to front-end development (angular, ember, backbone, etc.), it is also used in backend architectures such as node. reading JS and database data, such as MongoDB. The huge ecosystem built by JavaScript also makes it necessary for most jobs. Javascript itself is not too difficult to learn. If you want to understand some basic applications, refer to here.

Java

The second name on the list is Java, which accounts for 34.2%. Some people think that Java is an outdated language and that it is about to be eliminated. However, Java ranked second according to the ranking on tibench index (based on the popularity and popularity of programming languages. Not only has Java not been eliminated, but it is still a good backend language favored by many large enterprises. Java has been valued by enterprises. A major reason is not only because it is easy to use, but because learning java well makes it easier for you to learn other programming languages, because Java is an object-oriented language and does not need to process indicators (pointer), it has a good development environment (IDE) for beginners to use relatively simple, it can be said that as a software engineer, you must understand the basics. In my experience, Java is a little harder to learn than Javascript. Some resources on the Internet are not lacking. For example, MIT provides his course materials for free.

Html

The third name on the list is HTML. html is not strictly a programming language. It is a markup language ), simply put, the mark can be used to achieve different effects from the pure text. For example, you can add a hyperlink to the front and back of a text. HTML is the foundation of network development. It is necessary to understand every HTML Tag function in the front-end development. However, I still want to emphasize that he is not a programming language. If only HTML is not helpful for finding a job, he is just the basic. We also recommend a website where you can learn HTML in about one day.

SQL and nosql

In addition, what is listed on the list is that SQL is required in the 31.2% job shortage. According to the asurvey survey, 79% of respondents still use relational databases, which is why SQL is popular. However, this does not mean that nosql is not important. Although MongoDB only has 4.3% on the list, it is mainly used for products that require quick data access, such as Craigslist and Expedia.
Nosql and SQL are both good and bad. It has always been a widely debated topic in the database community. Most people think that nosql is the trend of the future, however, SQL still has the upper hand.

Javascript frameworks

The development framework built on JavaScript has a total of three angular. JS, Ember. JS, and backbone. js. These frameworks allow you to easily and quickly process front-end development. However, because these three development frameworks are similar in nature, there are also a lot of arguments about who is the best. Angular. JS, developed by Google, stands first on the list. Of course, these three development frameworks have their own advantages, such as angular. JS is suitable for large-scale development, backbone. JS is easier to learn, and backbone. js makes Cooperative Development easier.

Node. js

Node. JS is also mentioned in the original article because of its increasing users and the use of large companies such as LinkedIn and Wal-Mart.

Conclusion

Many programming languages and technology technologies are mentioned in the article. Some readers may think that they can find a job as a software engineer by touching each of the above items. There is no guarantee about the effect, but if you have a deep understanding of the specific skills, it will definitely help you find a job as a software engineer. Of course, as far as the author's experience in studying abroad and looking for a job is concerned, it is absolutely not necessary to find a software engineer. This part will be shared with readers next time.
