There are some indicators on TradingView website that are in pine script and I like to add them to chart library so I have them on my website. But I've done a lot of search, and didn't find how to do that. Any help would be appreciated.
This is on of those indicators that I like to convert to JavaScript:

sumw = 0.
for j = 0 to min(499,n-1)
w = exp(-(pow(i-j,2)/(h*h*2)))
sum += src[j]*w
sumw += w
y2 := sum/sumw
d = y2 - y1
l := array.get(ln,i)
line.set_xy1(l,n-i+1,y1)
line.set_xy2(l,n-i,y2)
line.set_color(l,y2 > y1 ? #ff1100 : #39ff14)
line.set_width(l,2)
if d > 0 and y1_d < 0
label.new(n-i+1,src[i],'▲',color=#00000000,style=label.style_label_up,textcolor=#39ff14,textalign=text.align_center)
if d < 0 and y1_d > 0
label.new(n-i+1,src[i],'▼',color=#00000000,style=label.style_label_down,textcolor=#ff1100,textalign=text.align_center)
y1 := y2
y1_d := d
There is no converter for such things. Pine Language has nothing to do with JavaScript, so you will need to write your own implementation for each function.
There is no converter for that. TradingView had provide a way to write custom indicators code using javascript. The guide link is below.

You can write your PineJs logic in javascript easily.
