I found this Gist for money formatting on Shopify using JavaScript https://gist.github.com/stewartknapman/8d8733ea58d2314c373e94114472d44c
I placed it in my cart page and when I try:
Shopify.formatMoney(2000, '$')
I get this:
cart:2166 Uncaught TypeError: Cannot read property '1' of null
at Object.Shopify.formatMoney (cart:2166)
at <anonymous>:1:9
this is at switch(formatString.match(placeholderRegex)[1]) {
I expect to get $20.00
Do you know where the problem is?

I found formatMoney
function in my theme and I was able to call it and it worked.
pipelineVendor.themeCurrency.formatMoney(2000);
result: $20.00
