    is-obj-props

    A small, yet very useful npm package, which is used to check if an object possess a property or not. Checks for any depth of nested objects

    • If the object has the property, it will return the value
    • If the property is not present, it returns 'null'

    Installation

    $ npm i is-obj-props

    How to Use

    Install and import is-obj-props

    import isObjProps from 'is-obj-props';
     
    const testObj = {
        name: "UserName",
        age: 25,
        marks: {
            exam1: 98,
            exam2: {
                part1: 47,
                part2: 48
            }
        }
    }

    isObjProps is a function which takes 2 arguements:

    • Arguement 1 - Type: Object - The Object to be tested (testObj in this case)
    • Arguement 2 - Type: Array - Array of Property names. The length of the array denotes the depth of the property in nested object.
    The examples will make you understand better

    console.log(isObjProps(obj, ["name"]));
    //UserName
     
    console.log(isObjProps(obj, ["FirstName"]));
    //null
     
    console.log(isObjProps(obj, ["marks","exam1"]));
    //98
     
    console.log(isObjProps(obj, ["marks","exam2"]));
    //{part1: 47, part2: 48}
     
    console.log(isObjProps(obj, ["marks","exam3"]));
    //null
     
    console.log(isObjProps(obj, ["marks","exam2","part2"]));
    //48
     
    console.log(isObjProps(obj, ["marks","exam2","part3"]));
    //null

    Benefits

    This never lets us face undefined error due to object properties again.
