Semantics3 Interview Questions and Answers

Efficiently process large amounts of data by using parallel processing, optimizing algorithms, and utilizing data structures.

• Utilize parallel processing techniques such as goroutines in Golang to process data concurrently.

• Optimize algorithms to reduce time complexity and improve processing speed.

• Use efficient data structures like maps, slices, and channels to store and manipulate data.

• Consider using caching mechanisms to reduce the need for repeated data processing.

• Implement ...read more

Go supports object-oriented programming principles through struct types and methods.

• Go uses struct types to define objects with fields and methods.

• Methods can be defined on struct types to provide behavior to objects.

• Go does not have classes like traditional OOP languages, but it supports encapsulation, inheritance, and polymorphism through struct embedding and interfaces.

Arrays are fixed-size collections of elements of the same type, while slices are dynamic arrays with a flexible size.

• Arrays have a fixed size determined at compile time.

• Slices are dynamic arrays that can grow or shrink.

• Arrays and slices are both zero-indexed.

• Arrays are passed by value, while slices are passed by reference.

• Example: var arr [3]string = [3]string{"apple", "banana", "orange"}

• Example: var slice []string = []string{"apple", "banana", "orange"}

Goroutines are lightweight threads managed by Go runtime, allowing concurrent execution of functions.

• Goroutines are created using the 'go' keyword followed by a function call.

• They are multiplexed onto multiple OS threads by the Go runtime.

• Goroutines communicate using channels to share data safely.

• They are more efficient than traditional threads due to their lightweight nature.

Go is simpler, more efficient, and easier to learn compared to C++.

• Go has a simpler syntax and is easier to read and write compared to C++.

• Go has built-in concurrency support with goroutines and channels, making it easier to write concurrent programs.

• Go has a garbage collector, which simplifies memory management compared to manual memory management in C++.

• Go compiles faster than C++ due to its simpler type system and lack of header files.

• C++ has more features and is more powe...read more

Life cycle hooks are functions that get called at specific stages of a component's life cycle.

• Angular provides several life cycle hooks that allow you to tap into specific moments in a component's life cycle.

• Some common life cycle hooks include ngOnInit, ngOnChanges, and ngOnDestroy.

• ngOnInit is called after the component has been initialized and its inputs have been bound.

• ngOnChanges is called whenever one or more of the component's input properties change.

• ngOnDestroy is call...read more
