pub const MAX_STRING_LENGTH: usize = 536_870_888;Expand description
V8’s String::kMaxLength on a 64-bit build, in UTF-16 code units — the
largest string the engine will materialize.
Measured on node v26.7.0 (darwin arm64):
require('buffer').constants.MAX_STRING_LENGTH is 536870888,
'a'.repeat(536870888) succeeds with that length, and
'a'.repeat(536870889) is RangeError: Invalid string length.
