ANSI Escape Sequences
The standard means of terminal control, consisting of the ESC character followed by control instructions. They are used to implement functions such as colors, cursor movement and screen clearing. Modern terminals support 256 colors and even true color.

ANSI escape sequences are a standard set of control instructions embedded in text streams, originating from the VT100 terminal specification in the 1970s.
The ANSI escape sequence format typically begins with ESC[, for example ESC[2J clears the entire screen, ESC[H moves the cursor to the upper-left corner, and ESC[31m colors subsequent characters red.
The efficient approach to terminal animation is to send update instructions only for cells that have changed (delta updates) rather than clearing the entire screen each frame, in order to reduce flickering and write volume.
