JavaScript - ANSI Escape Codes

ANSI sequences were introduced in the 1970s to replace vendor-specific sequences and became widespread in the computer equipment market by the early 1980s.

They were used by the nascent bulletin board systems to offer improved displays compared to earlier systems lacking cursor movement, a primary reason they became a standard adopted by all manufacturers.

See the video Connect: A Look At Bulletin Board Systems

Certain sequences of bytes, most starting with Esc and [, are embedded into the text, which the terminal looks for and interprets as commands, not as character codes.

• \033 begins the escape sequence
• [ indicates the color
• 33 is the foreground color for yellow
• m indicates the end of the setting

Note: \033[39m is used set the color back to the terminal default

console.log('\033[33m Hello World \033[39m');

This will give a nice yellow color Hello World.
