Sierpiński triangle

//with 32
m=32;
pt=PASCALTRIANGLE(m).$(x=>x%2)
a=pt
	.map(
		function (r,i)
		{
			var prefix= (REPEATCHAR(" ",(2*m-(2*i+1))/2).split(""));
			 return(
				  prefix
		 			.concat(r.join(", ,").split(","))
		 			.concat(prefix)
			)
		}
	);
(a);

Fibonacci and Pascal Triangle

FIBONNACI(100)
b=PASCALTRIANGLE(100)
b.map(
	function calcfib(r,i,d)
	{
		var fib=0;
		var j=0;
		for(var xi=i;xi>=0;xi--)
		{
			fib+=isNaN(d[xi][j])?0:d[xi][j];
			j++;
		}
		return(fib)
	}
)

Pretty Pascal Triangle

m=10;
pt=PASCALTRIANGLE(m)
pt
	.map(
		function (r,i)
		{
			var prefix= (REPEATCHAR(" ",(2*m-(2*i+1))/2).split(""));
			 return(
				  prefix
		 			.concat(r.join(", ,").split(","))
		 			.concat(prefix)
			)
		}
	);
