"a": The start of the "assert" keyword in the static import statement
"as": The { start of the assertion
"ae": The } end of the assertion
For dynamic imports, "as" and "ae" are not used, instead only "a":
"a": The index immediately after the , - so { in the dynamic import expression import('specifier', {...})
"e": Is updated to reference the end of the specifier portion before the , in the import expression, instead of the position before the closing ). This is effectively a breaking change to the dynamic import handling.
"ss": Remains but is now documented as the start of the dynamic import(... expression itself.
"se": Is updated to reference the end of the import expression (position of the closing )).

Adds support for parsing import assertions.
Three variables are used -
"a","as"and"ae".For static imports these correspond to:
"a": The start of the"assert"keyword in the static import statement"as": The{start of the assertion"ae": The}end of the assertionFor dynamic imports,
"as"and"ae"are not used, instead only"a":"a": The index immediately after the,- so{in the dynamic import expressionimport('specifier', {...})"e": Is updated to reference the end of the specifier portion before the,in the import expression, instead of the position before the closing). This is effectively a breaking change to the dynamic import handling."ss": Remains but is now documented as the start of the dynamicimport(...expression itself."se": Is updated to reference the end of the import expression (position of the closing)).Resolves https://github.com/guybedford/es-module-lexer/issues/73.
