To use the propertyIsEnumerable
function from the fs-extra
library in TypeScript, follow the steps below:
@types/fs-extra
package by running the following command:index.ts39 chars2 lines
fs-extra
library in your TypeScript file:index.ts32 chars2 lines
propertyIsEnumerable
function from the fs-extra
library to determine whether an object has the specified property as a direct property of that object:index.ts177 chars4 lines
The first console.log
statement returns true
because the myObject
has the name
property and it is enumerable. The second console.log
statement returns false
because the myObject
object does not have the toString
property as a direct property.
Note: This function is particularly useful for checking whether an object has an own property defined on itself, as opposed to inheriting it from its prototype chain.
