how to use the propertyisenumerable function from the underscore library in javascript

To use the _.propertyIsEnumerable function in the Underscore library, first, we need to include the Underscore library in our project. We can either download the library and include it in our HTML file using a script tag, or we can use a Content Delivery Network (CDN) link.

After that, we can use the _.propertyIsEnumerable function to check if a property is enumerable or not. The function takes an object and a property name as its arguments and returns a boolean value indicating whether the specified property is enumerable or not.

index.tsx
const car = {
  make: 'Ford',
  model: 'Mustang',
  year: 2022
}

console.log(_.propertyIsEnumerable(car, 'make')); // true
console.log(_.propertyIsEnumerable(car, 'toString')); // false

In the above example, we have an object car with three properties: make, model, and year. We have used the _.propertyIsEnumerable function to check if the make property is enumerable or not, which returns true. We have also checked if the toString property is enumerable or not, which returns false, as toString is a non-enumerable property.
