Variable substitution

If an identifier starts with $, it is substituted with the value of the parameter passed.

e.g.

use swc_common::DUMMY_SP;
use swc_ecma_ast::Ident;
use swc_ecma_quote::quote;

// This will return ast for `const ref = 4;`
let _stmt = quote!("const $name = 4;" as Stmt, name = Ident::new("ref".into(), DUMMY_SP));

// Tip: Use private_ident!("ref") for real identifiers.

Examples

Quote a variable declaration

use swc_common::DUMMY_SP;
use swc_ecma_ast::Ident;
use swc_ecma_quote::quote;

// This will return ast for `const ref = 4;`
let _stmt = quote!("const $name = 4;" as Stmt, name = Ident::new("ref".into(), DUMMY_SP));

// Tip: Use private_ident!("ref") for real identifiers.
