As a senior abap consultant, which SAP technology can be selected as the main direction in the next step?

A friend asked me for advice ：

About this topic ,Jerry Once wrote an article ：ABAP What should developers learn in the future .

Its English version Published in the SAP On the community blog and topped by administrators , Got over 10000 readings .

The four learning directions I suggested in the article at that time were ：

(1) Familiar with a functional programming language
(2) understand Spring
(3) be familiar with JavaScript
(4) Learn about a NoSQL database

Then I added the fifth point , be familiar with SAP Cloud Platform ( Now it's changed to SAP Business Technology Platform） Development technology .

and SAP UI5 The framework provides a framework for application implementation Fiori UX Native support for page style , That's what some developers jokingly call “SAP UI5 It's just SAP The son of front end development ”.

SAP UI5 As including SAP Flagship products S/4HANA And many other front-end technologies for cloud products , This shows that it is in SAP The core of the technology family . so to speak , as long as S/4HANA The flag will not fall , Application developers invest in ABAP + SAP UI5 It's a combination of time and energy , It will never be in vain .

meanwhile , In recent years ,SAP A lot of development resources have been invested , around SAP UI5 Building its ecosystem , Launched such as UI5 WebComponents,UI5-tooling,UI5 Easy Generator,UI5 Inspector,UI5 CLI,UI5 Builder,Karma for UI5,Fiori Elements And other development libraries , Development framework and development tools . therefore , Study SAP UI5, There will be opportunities to access these surrounding SAP UI5 The new technology fields derived from it , Broaden yourself except ABAP Beyond the technological horizon .

On the other hand , I'm learning SAP UI5 Application build , distribution , And when deployed to the cloud server , By using SAP UI5 Tooling Tools such as , We can reach the server side again JavaScript Basic knowledge of , namely Nodejs.
