Brief Programming languages have the notion of constants which means “variables that can not be mutated once declared and initialized”. Go also has almost the same meaning, but in a different context. To initialize a variable as a constant with a value of 10, we can do something like this: const DISCOUNT = 10 In Go, constants mean “storing a literal to a variable”, this can be seen as a version of pattern matching in Erlang....

I found dot-prop npm package, which solves it quite well. But going through this gist, I found this answer. The author said a “functional way to solve it”… And this right here, is an example of declarative programming....
As a software engineer, I have written a lot of lines of code, and taking hindsight back to the very first day of my career, I have written a log of bad code. I recently published a new version of my react-here-maps library which saw a sprinkle of my improved skill set. I had a coding interview where I was tasked to add functionality to support extra data points of the original response and think about adding weeks, months, and years to data that only returned days....
In Ruby, the if statement looks like this val = 1 if val == 1 p "Equality Checked!" end And for if else val = 2 if val == 1 p "Equality Checked!" else p "Equality Unchecked!" end And for if, else if, else val = 2 if val == 1 p "Equality Checked!" elsif val == 2 p "Equality Middle Checked!" else p "Equality Unchecked!" end Also, remember that everything in ruby returns a value, so your if statement can return a value that could be stored in another variable....
