Returns true if a value has the characteristics of a valid JavaScript accessor descriptor.
const isAccessorDescriptor = require('is-accessor-descriptor'); const assert = require('assert'); const obj = { get foo() {}, bar: { get: function() {} } }; assert.equal(true, isAccessorDescriptor(obj, 'foo')); assert.equal(false, isAccessorDescriptor(obj, 'bar')); // or, if you already have the descriptor you can pass it directly const foo = Object.getOwnPropertyDescriptor(obj, 'foo'); assert.equal(true, isAccessorDescriptor(foo)); const bar = Object.getOwnPropertyDescriptor(obj, 'bar'); assert.equal(false, isAccessorDescriptor(bar));You might also be interested in these projects:
