A data flow node that writes to an object property.
For example, all of the following are property writes:
obj.f = value; // assignment to a property
obj[e] = value; // assignment to a computed property
{ f: value } // property initializer
{ g() {} } // object literal method
{ get g() {}, set g(v) {} } // accessor methods (have no rhs value)
class C {
constructor(public x: number); // parameter field (TypeScript only)
static m() {} // static method
g() {} // instance method
}
Object.defineProperty(obj, 'f', { value: 5} ) // call to defineProperty
<View width={value}/> // JSX attribute
