Length() function considers other functions

[GHNewbiee]

Example:

msg = 'This is red text'
text = `{$chalk.red(msg)}`;
console.log(text) // This is red text
text.length === 16 // false

Can I get more information on what you mean?

[GHNewbiee]

Yes, sure. Please run the following js code.

import chalk from 'chalk';

const msg = 'This text length should be 30.';
const msgLength = msg.length;
console.log(msg, "\tIndeed, it's:", msgLength);
const text = chalk.red(msg);
const textLength = text.length;
console.log(text, "\tUnfortunately, it is not; it's ", textLength, ". Why?");

I could be wrong but I think chalk.red() is just inserting ANSI escape sequences into the string - so there are more characters there, they are just invisible
