It seems you are going for a start up company (which has urgency of any candidate they can get) as big MNC companies usually don't hire candidate without evaluation. Yet, You never know what this opportunity might bring you in terms of learning however you should have doubts like: What is the project they are hiring for? For how long you will be working on this project? How will the company sustain you in case of any money crisis they face in future? I believe, asking these question to the company's HR will help you take better decision. Happy Coding :) !!
It is totally dependent on your requirement but to cut the long discussion short. Mongoose is an Object modeling tool to design your MongoDB's collection schema within your application and it is built on top of the Native MongoDB driver to allow us to access the database. Edit: Native MongoDB driver is faster. Happy Coding!!
Iterator in java is used to iterate Collection to retrieve elements one by one. Iterator interface defines these two methods : public boolean hasNext(); // Returns true if the iteration has more elements public Object next(); // Returns the next element in the iteration This can be understand by a simple code snippet shared below: ArrayList names = new ArrayList(); names.add( "jack" ); names.add( "james" ); names.add( "Don" ); Iterator it = names.iterator(); while (it.hasNext()) { // it.hasNext() checking if iterator has next value? String name= (String)it. next (); // it. next () returning the next value System.out.println(name); } Hope this will clear your doubt. Happy Coding!!!
there is always a solution for every problem . Lets think about it, we as a programmer often stuck with programming problem and might spend days to find a solution of these problems. every day we debug issues, bugs , sometime when we do not find solution look for the help of colleagues, lead or internet but eventually you get something which solves your problem, which can be direct of indirect but you always find a solution of every problem. Happy coding and keep solving problem, Because there is always a solution for every problem !!
UPSERT in MongoDB is used to create a new document while no document matches the query criteria, it is an optional parameter you can give in UPDATE query. For Example: there is list you document containing names db.collection.find(); { " _id " : ObjectId( "5b0d1a2e44d67bdc91e63816" ), " name " : "amy" } { " _id " : ObjectId( "5b0d1a3d44d67bdc91e63817" ), " name " : "jack" } Think about a situation where you do not have document with name ben in your collection and you are still updating the value to Lee , setting up UPSERT option to true will create one document with name Lee even if it does not find document where name is ben . Below is the update query with use of UPSERT db.collection.update({ "name" : "ben" }, { "name" : "Lee" }, {upsert: true }); Below is the document created after use of UPSERTin update query. { " _id " : ObjectId( "5b0d2d8a72d07236a420a333" ), " name " : "Lee" } Hope this answer will help you understand the use of UPSERT. Happy coding!!
Prior to get into Spring-boot, one has to have a good understanding of Java. As you said, you already have solid understanding of Java, you are ready to dive into Spring Boot framework. If you are looking forward learning Spring Boot framework, it will be fun if you Learn it by implementing (try develop application) instead of learning the concept directly. there are so many good tutorial are already available in internet find one and try develop an application. Spring Boot is a Java framework which itself make development easy, any (SQL, No-SQL ) Database connectivity and development of Stand alone Application have never been easier. Shared link is tutorial series you might find helpful with your learning. Happy coding!!
I believe, you do not need a degree to get a job if you are good at something. to prove the statement let me tell you a story(A true story) of a guy whom i met in a technical meetup. On first look, i found him very simple looking and very good at programming but not very confident. so during the conversation with him he told me about him and his story is been quite motivational to me as well. He used to work in a computer cafe and there is when he got his first desire to learn programming language after he saw some guys discussing and coding in his cafe, then he learned HTML, JavaScript by help of these guys and from google and different free resources. and finally got his job as UI developer in very small scaled company where he used to get Rs. 4000. I sure was good with technologies and eager to learn new things, he learned ReactJS which was new to that time, As for degree Initially he did not had degree but he did distance BCA for a degree and later on got job in very good MNC company. Here is what is learned from this is: you do not need degree to get started, if you are good at something everyone will value you. Degree and certificates are just a way to show case your skills (Which can help you to get recognize by companies and you will not get filtered out from the criteria). Hope this answer will help you. Happy coding!!
I assume you already know what is MEAN stands for, but a little intro is essential. MEAN is a technology stack which includes [ M ongoDB as Database | E xpressJS as NodeJS framework to write restful APIs, A ngularJS as FrontEnd(UI), N odeJS as Backend] (NOT to be confused - NodeJS is backend side javascript and ExpressJS is Framework on NodeJS to write Restful APIs Simply), it helps you to create Web Appliaction quickly. Learning MEAN Stack becomes very simpler if you have background in JavaScript, As NodeJs is server side JavaScript you can understand and get used to it easily. you have to put a little effort to learn MongoDB if you do not know anything about this DB. Little background in Any NoSql DB can make it easier to learn. If you wants to get start with latest version of AngularJS 4 or so, i suggest to have a look in this link . which is a step by step implementation of MEAN stack using Angular 4. Hope this will help you. Happy coding!!
