ObjectTag

enum ObjectTag

objectToString returns strings like "[object Array]"; this enum gives those strings names, so a comparison reads as ObjectTag.ARRAY rather than as a literal that a typo can quietly break.

Several guards in the library are built on it — it is how isRegExp and isFunction recognise a value that crossed a frame boundary, where instanceof no longer holds.

Examples

Shape

objectToString([]) === ObjectTag.ARRAY; // => true objectToString(null) === ObjectTag.NULL; // => true
