JavaScript is a versatile and powerful language, but with
great power comes great responsibility. One feature that you
should handle with care is the
eval() function. In this
concise guide, we’ll explore why it’s best to avoid
eval() and seek alternative
solutions.
In the world of JavaScript, cleaner and more readable code is
a prized possession. Object shorthand is a handy technique
that can help you achieve just that. In this concise guide,
we’ll explore what object shorthand is and how it can simplify
your code.
JavaScript offers powerful tools for working with arrays –
map,
filter, and
reduce. In this concise
guide, we’ll uncover the magic of these functions and how they
can level up your data manipulation game.
Are you ready to unlock a magical feature in JavaScript that
can make your code more elegant and readable? Say hello to
“Destructuring”! In this beginner-friendly guide, we’ll
explore what destructuring is and how it can simplify your
code.
One of Python’s standout features is its ability to perform
complex tasks with simplicity and readability. One area where
this shines is dictionary comprehension with conditional
expressions. In this blog post, we’ll delve into this
technique, exploring how it can streamline your code and
enhance your Python programming skills.
Python’s implicit line continuation is a powerful feature that
allows you to break long lines of code without the need for
backslashes or explicit continuation characters.
By enclosing expressions within parentheses, brackets, or
curly braces, Python recognizes the continuation and treats
the code as a single logical line.
In this article, we will explore implicit line continuation
and provide code examples to illustrate its usage and
benefits.
One way to improve the concision of your Python code is by
using the ternary operator, a handy tool that allows you to
condense an if-else statement into a single line of code.
Let us jump straight into it.
Imagine that you have the following comparison:
x = 5
y = 10
if x > y:
result = x
else:
result = y
Finding the number of days is usually quite popular and well
documentated. There can also be cases when we need to find a
difference in terms of weeks or even months.
If you want to find the difference in months between 2 dates,
then here is a quick Python script to help you do that.
For example, between October 2018 and November 2021, there
isn’t just a month difference. There is also a difference in
years as well.
Let us assume that we don’t have dates prepared yet, so we
initialize 2 variables with 2 dates.
After that, we find the difference in terms of number of
months in between.
We should keep in mind that we may have dates that are in
different years, and it’s not enough to think that we can just
subtract two dates. Because of that, we need to also find the
difference in years.
Here is the entire script:
You may get the impression that we may have a negative number
in the end, since we are subtracting the number representing a
month from another month.
To illustrate, let us assume that we have the following:
Now, since we are subtracting the number of months from the
first date and 3 < 12, we will indeed get -9. However, we
also have in the end a difference in years that is equal 1,
since 2021 – 2020 = 1.
Hence, we will add 12 to -9, and in the end we get the result
equal to 3:
