- Step 1: Know what you need to study. You already know what programming language you will be using, so now you need to research what aspects of that language will be tested.
- Step 2: Make a plan.
- Step 3: Don’t forget the behavioral interview.
What would be the result of 3+2+”7″? Since 3 and 2 are integers, they will be added numerically. And since 7 is a string, its concatenation will be done. So the result would be 57.
A promise is an object that may produce a single value some time in the future: either a resolved value, or a reason that it’s not resolved (e.g., a network error occurred). Promises are eager, meaning that a promise will start doing whatever task you give it as soon as the promise constructor is invoked.
What is the best language for coding interviews?
C. C is positioned at #1 with 13.83% ratings, followed by Python, Java, and C++. C, Python, and Java make for a good combination of languages to build a solid coding foundation. Being developed in the 70s, C forms the basis of many new languages such as Python and Ruby.
Async/await makes your code look synchronous, and in a way it makes it behave more synchronously. The await keyword blocks execution of all the code that follows it until the promise fulfills, exactly as it would with a synchronous operation.
