Lato Code font is a derivation of Lato by Łukasz Dziedzic. It alters some of the glyphs in order to make the font suitable for displaying source code, using a beautiful, easy-to-read and space-optimizing proportionally spaced font.
Lato Code comes in Regular, Italic, Bold, and Bold Italic. Lato Code's Bold typeface is actually Lato's Black typeface. This is because most editors (Visual Studio Code) only support the display of two separate fonts weights in the editor, and the font strives to maximize visual differentiation where possible.
