size < 2 -> this

else -> {

val pivot = first()

val (smaller, greater) = drop(1).partition { it <= pivot }

smaller.quickSort() + pivot + greater.quickSort()

}

Characters remain standard in width, but the height of the lowercase is maximized. This approach keeps code lines to the length that developers expect, and it helps improve rendering since each letter occupies more pixels.

Consider this in contrast to some other fonts. Consolas, for example, has slightly wider letters. However, they are still rather small, which forces you to increase the size by one point to make the font more readable. As a result, lines of code tend to run longer than expected.

JetBrains Mono’s standard-width letters help keep lines to the expected length.

The shape of ovals approaches that of rectangular symbols. This makes the whole pattern of the text more clear-сut.

The outer sides of ovals ensure there are no additional obstacles for your eyes as they scan the text vertically.

JetBrains Mono’s typeface forms are simple and free from unnecessary details. Rendered in small sizes, the text looks crisper.

The easier the forms, the faster the eye perceives them and the less effort the brain needs to process them.

“1”, “l”, and “I” are all easily distinguishable from each other.

The zero has a dot inside. The letter “O” does not.

The comma’s shape differs from that of the period, making them easier to tell apart at small sizes. The same holds true for derived symbols, as well.

A radical cut at the end of strokes fits the pixel grid better and gives the typeface a stricter and more ‘tech’ personality.

The key to good italiсs is the fine-tuning of the contrast between upright and italic font. Typically, the angle is about 11°–12°. JetBrains Mono uses a 9° angle; this maintains the optimal contrast to minimize distraction and eye strain.

Only for “a”, “y”, and “f” is the construction taken from True italic 2 to slightly enhance the horizontal flow for the eyes.

A ligature is a character consisting of two or more joined symbols. Traditionally, it was introduced as a space-saving technique in printed texts. In code, this technique is adopted to show operators and is used mainly for two purposes:

1.

To reduce noise by merging symbols and removing details so the eyes are processing less.

2.

To balance whitespace more efficiently by shifting the glyphs in certain cases.
