Monospaced Font with Programming Ligatures
Don't Use Programming Ligatures Font
Ligature font means it combines a sequence of 2 or more characters and display them as a single glyph.
e.g.
-> is displayed as →.
Fira Code began the code ligature fad of zoomers, around 2014.
Ligature font is no good. You want to see char as is, not seeing middlemen. It adds complexity for a little prettiness.
If you wanna see pretty characters such as lambda displayed as λ, use a programing language that allow unicode in name or operators directly.
