this.node = ts.createSourceFile("code.ts", "foo.substring(1, 2)")
this.code = "{{expression.name}}"
rewrittenSource() // substring

// node array
const node = ts.createSourceFile("code.ts", "foo.substring(1, 2)")
rewrittenSource(node, "{{expression.expression.expression}}.slice({{expression.arguments}})") // foo.slice(1, 2)

// index for node array
const node = ts.createSourceFile("code.ts", "foo.substring(1, 2)")
rewrittenSource(node, "{{expression.arguments.1}}") // 2

// {name}Property for node who has properties
const node = ts.createSourceFile("code.ts", "const foobar = { foo: 'foo', bar: 'bar' }")

// {name}Initializer for node who has properties
const node = ts.createSourceFile("code.ts", "const foobar = { foo: 'foo', bar: 'bar' }")
