This new ES7 feature made my math 3 times easier
But 5 lines of Java is one line of Python.
How many times have you heard something like that from lovers of the later?
Seems like they love to trash languages they stubbornly believe are verbose. I came to see that “Pythonic” is something truly cherished by our friends in the Python community.
Your Python code works, and so what? Where is elegance? Where is readability?
Think you can write a simple for loop and get away with it?
total = 0 for i in range(1, 11): total += i print("The sum of the first 10 numbers is:", total)
Just wait till one of them find out — to say you’ll face severe criticism is an understatement.
Because apparently — and I kind of agree — it’s just not “beautiful” or concise enough.
To be “Pythonic” is best.
total = sum(i for i in range(1, 11)) print("The sum of the first 10 numbers is:", total)
11 Amazing New Features in ES13
An ES7 feature that brings syntactic sugar and conciseness
This one almost always comes up in Python’s favor when talking about language conciseness, up there with generators and the
It’s now effortless to get the power of a number, with the
** operator. Instead of
Math.pow(a, b), you do
a ** b.
const result = Math.pow(10, 2); console.log(result); // 100 const result2 = Math.pow(2, Math.pow(3, 2)); console.log(result2); const result3 = 10 ** 2; console.log(result3); // 100 const result4 = 2 ** 3 ** 2; console.log(result4) // 512
We don't need a function for such a common math operation anymore.
You can even pass a decimal number as a power with
Math.pow() can do this too:
const result = Math.pow(49, 1.5); console.log(result); // 343 const result2 = 49 ** 1.5; console.log(result2); // 343
And it's not only a drop-in replacement for
** can take BigInts too:
// ❌ Error: Cannot convert a BigInt value to a number const result1 = Math.pow(32n, 2); console.log(result1);
const result2 = 32n ** 2n; console.log(result2); // 1024n
BigInts let us represent numbers of any size without losing precision or experiencing overflow errors.
const veryLargeNumber = 1234567890123456789012345678901234567890n; console.log(typeof veryLargeNumber); // "bigint" console.log(veryLargeNumber * 2n); // 2469135780246913578024691357802469135780n
You can see that we simply add an
n at the end of the digits to make it a
Language wars are a fun programmer pastime.
It’s always fun to debate about which programming language is more elegant and concise.
But at the end of the day, we’ve got to keep in mind that writing readable and maintainable code is what matters most.
In this article, we saw that the
More features keep getting added every year — ES13 was released in 2022 — to increase and add more syntactic sugar.
So, keep exploring the possibilities of your favorite programming language, and have fun coding!
