AngularJS developer Interview Questions
The days are gone when a Front-end Developer used to be the one, who has a good knowledge of HTML, CSS and JavaScript only.
Although, the languages are still the same, but frameworks like AngularJS, ReactJS in Javascript have brought so much ease and speed to the development, that now the profile of Front-end Developer is used to be called by the name like AngularJS, ReactJS Developer, etc.
Again, there comes a question in every developer mind that what is the most trending in the market, AngularJS or ReactJS ?
Some says React is better, some says Angular 2.0, but as of current market condition it is the Angular 1 in which most of the development has been done so far and companies are looking for the people who are having deep understanding of Angular 1 with the knowledge of Angular 2.0 and ReactJS as an added advantage.
There is no doubt, that the future will be either of React or Angular 2.0 , but still time is there for the companies to get fully adopted to these frameworks leaving Angular 1 far behind.
