Multiline strings infinite loop

There’s a weird thing that happens when you use multiline strings with the rainbow animation:

sample:

chalkAnimation.rainbow(`tripping on rainbow road`); // is OK

chalkAnimation.rainbow(`
tripping on rainbow road`); // infinite loop of newlines

All right, with a logo this big I can understand why the performance is bad.

Anyway, if you still want some fancy 🌈 without the animation, I suggest you gradient-string, another project of mine

chalk-animation cannot do it, but you do!

const logo = [ 
	"  __",
	"<(o )___",
	" ( ._> /",
	"  `---'",
].join('\n');

const cls = `\u001b[2J\u001b[0;0H`;

const rainbow = chalkAnimation.rainbow(logo).stop(); // Don't start the animation

setInterval(function () {
	console.log(cls); // Clear screen
	rainbow.render(); // Render a frame
}, 15);

The \u001b[2J escape code will clear the screen, and \u001b[0;0H will put the cursor at 0,0 (optional, will render differently if you remove it).
