Binding

external is like a let binding, but:

• The right side of = isn't a value; it's the name of the JS value you're referring to.
• The type for binding is mandatory.
• Can only exist at the top level of a file or module.

Binding to JS global functions - Js.Global

Refs

• rescript-js
• rescript-webapi

Illegal identifier

Illegal identifiers can be created by prefixing \.

let \"orange 🍊" = "🍊"
\"orange 🍊"->Js.log

type element = {
  \"aria-label": string
}

let myElement = {
  \"aria-label": "close"
}

let label = myElement.\"aria-label"

let calculate = (~\"Props") => {
  \"Props" + 1
}
