Source

The constructor property returns a reference to the Object constructor function that created the instance object.

MDN documentation

Source

👎Deprecated: Use Object::hasOwn instead.

The hasOwnProperty() method returns a boolean indicating whether the object has the specified property as its own property (as opposed to inheriting it).

MDN documentation

Source

The isPrototypeOf() method checks if an object exists in another object’s prototype chain.

MDN documentation

Source

The propertyIsEnumerable() method returns a Boolean indicating whether the specified property is enumerable.

MDN documentation

Source

The toLocaleString() method returns a string representing the object. This method is meant to be overridden by derived objects for locale-specific purposes.

MDN documentation

Source

The valueOf() method returns the primitive value of the specified object.

MDN documentation

Source

Returns the f64 value of this JS value if it’s an instance of a number.

If this JS value is not an instance of a number then this returns None.

Source

Tests whether this JS value is a JS string.

Source

If this JS value is a string value, this function copies the JS string value into Wasm linear memory, encoded as UTF-8, and returns it as a Rust String.

To avoid the copying and re-encoding, consider the JsString::try_from() function from js-sys instead.

If this JS value is not an instance of a string or if it’s not valid utf-8 then this returns None.

§UTF-16 vs UTF-8

JavaScript strings in general are encoded as UTF-16, but Rust strings are encoded as UTF-8. This can cause the Rust string to look a bit different than the JS string sometimes. For more details see the documentation about the str type which contains a few caveats about the encodings.

Source

Returns the bool value of this JS value if it’s an instance of a boolean.

If this JS value is not an instance of a boolean then this returns None.

Source

Tests whether this JS value is null

Source

Tests whether this JS value is undefined

Source

Tests whether this JS value is null or undefined

Source

Tests whether the type of this JS value is symbol

Source

Tests whether typeof self == "object" && self !== null.

Source

Tests whether this JS value is an instance of Array.

Source

Tests whether the type of this JS value is function.

Source

Tests whether the type of this JS value is bigint.

Source

Tests whether the value is “truthy”.

Source

Tests whether the value is “falsy”.

Source

Applies the binary / JS operator on two JsValues, catching and returning any RangeError thrown.
