    10 Skills to Look For In A Talented JavaScript Developer

    1. Expertise With JavaScript

    The first thing a JavaScript developer must master is the coding language. As a dynamic and prototype-based language, it’s necessary to understand the paradigm and control flow.

    2. Client-Side Framework & Libraries

    Client-side frameworks and libraries allow JavaScript Developers to access higher-level API to perform better by writing less code. Each client-side framework is different, but they all address compatibility, security, and accessibility.

    3. Asynchronous Programming

    From code review to pair programming, an experienced JavaScript developer is used to asynchronous programming.

    4. Cross-Browser Code

    A JavaScript developer must be able to write cross-browser code, creating compatible software for multiple browsers.

    5. React JS

    React JS is one of the most popular JavaScript libraries that allows interactive and user-friendly interfaces to be created quickly and efficiently.

    6. Redux

    Redux is a React state management system. With Context API, Redux is crucial to exploit React e-commerce functionalities’ performance.

    7. Node JS

    Node JS is a run-time tool for Back-end frameworks and ensures high performance and maintenance of the running application.

    8. Git

    Git is a version control system to track coding changes and facilitate asynchronous coding and remote workflow.

    9. TypeScript

    TypeScript is a transpile to clean ES5 code, reducing browser compatibility, safety, and scaling difficulty issues.

    10. jQuery

    Free and open-source software jQuery library simplifies HTML DOM tree traversal and manipulation, from CSS, animation, to Ajax. Also, it’s available.

    Best Javascript Developer interview questions

    For initiate Developers

    1. What is DOM?

    DOM is the Document Object Model and is used by HTML to represent the elements and contents of a page.

    JavaScript can be used to manipulate this model, which is why it’s such a prevalent language in  web development.

    2. What are the data types JavaScript uses?

    There are both primitive types and non-primitive types. Primitive types represent basic types such as numbers and strings.

    typeof ‘DistantJob’ // Returns “string”
    typeof “DistantJob” // Returns “string”
    typeof 5 // Returns “number”
    typeof 5.5 // Returns “number”
    typeof true // Returns “boolean”
    typeof 178233587725359997576391063983941630941986816n // Returns bigint
    typeof undefined // Returns “undefined”
    typeof null // Returns “object”, a common pitfall of JavaScript
    typeof Symbol(‘symbol’) // Returns Symbol

    Non-primitive types can be objects housing complex data structures (such as a vector or a coordinate) or arrays to store variables.

    var vector = {
        x: 10,
        y: 5.0,
        z: 10.5
    }

    var array = [“A String”, 5, false]

    3. What is Implicit Type Coercion in JavaScript?

    When operations are performed between two variables of different data types, JavaScript automatically converts the types in order to carry out the operation.

    When adding a number to a string, the number is automatically converted to a string as well.

    var a = 5;
    var b = “5”;

    a + b // Returns “55”

    However, when subtracting the opposite occurs and the string is converted to a number.

    var a = 5;
    var b = “5″;

    a – b // Returns 0

    4. What are the differences between the comparisons “==” and “===”?

    This answer is closely related to the Implicit Type Coercion mentioned above.

    • “==” is used to compare values
    • “===” is used to compare both values and data types
    var a = 5;
    var b = “5”;

    (a == b) // Returns true, since the values are the same
    (a === b) // Returns false, since a is a number and b is a string

    5. What are callbacks?

    Callbacks are functions that get executed when certain conditions are met (usually at the end of a function’s execution). They can be passed as parameters to another function so it can be executed inside its body or stored as an object’s property. It’s commonly used to signal a function´s correct or incorrect execution. 

    function odd(value){
      console.log(value + ” is odd!”);
    }

    function even(value){
      console.log(value + ” is even!”);
    }

    function checkNumber(num,oddFunction, evenFunction){
        if(number % 2 == 0) {
            evenFunction(num);
        } else {
            oddFunction(num);
        }
    }

    checkNumber(“5, odd, even); // Prints “5 is odd!
    checkNumber(10, odd, even); // Prints “10 is even!

    For Experienced Javascript Developers

    1. What are the differences between declaring variables with the keywords var, let and const?

    When the ECMAScript 6 (ES6) version was introduced in 2015, it introduced two new keywords to declare variables outside the traditional global scope of the var keyword: let and const. These add further control to the accessibility of variables within the code:

    var let const
    Global Scope Yes No No
    Function Scope Yes Yes Yes
    Block Scope No Yes Yes
    Can be reassigned? Yes Yes No

    2. What is the prototype design pattern?

    The prototype design pattern allows developers to set up default values for objects, initializing them. It is commonly used to define functions inside objects before the introduction of ES6 or to define new properties of existing object constructors.

    function Person(name,age){
      this.name = name;
      this.age = age;
    }

    Person.prototype.job = “JavaScript Developer”;


    Person.prototype.getDetails = function() {
        return “Name: “ + this.name + “, Age: “ + this.age + “, Job: “ + this.job;
    }

    var damian = new Person(“Damian”, 31);
    damian.getDetails(); // Returns “Name: Damian, Age: 31, Job: JavaScript Developer”

    3. What are classes in Javascript?

    Classes were introduced in ES6 and are syntactic sugar for constructor functions. These objects  hold pertinent data and can house functions to operate over said data.

    Before ES6, to emulate classes, you’d have to do something like:

    function Person(name,age){
      this.name = name;
      this.age = age;
    }

    Person.prototype.getDetails = function(){
      return ‘Name: ${this.name}, Age: ${this.age}’;
    }

    var anna = new Person(“Anna”, 16);
    anna.getDetails(); // Returns “Name: Anna, Age: 16”

    With ES6, this while process got much simpler with the introduction of proper classes:

    class Person{
        constructor(name,age){
            this.name = name;
            this.age = age;
        }

        getDetails(){
            return ‘Name: ${this.name}, Age: ${this.age}’;
        }
    }

    let ian = new Student(“Ian”, 22);
    ian.getDetails(); // Returns “Name: Ian, Age: 22”

    4. What are arrow functions?

    Also introduced in ES6, arrow functions are ways to declare expression-based functions with shorter syntax.

    Before ES6, functions needed to be declared as:

    var square = function (num) {
        return num * num;
    }

    var sum = function (num1, num2) {
        return num1 + num2;
    }

    In ES6, they can be declared as:

    var square = num => num * num;

    var sum = (num1, num2) => num1 + num2;
    1. What is the rest parameter?

    Another functionality introduced in ES6, the rest parameter allows functions to receive an undefined number of arguments.

    var sumAll= function (…inputs) {
        let sum = 0;
        for(let i of inputs){
            sum += i;
        }
        return sum;
    }

    // These calls are valid
    sumAll(1);
    sumAll(1, 2);
    sumAll(1, 2, 3);
    sumAll(1, 2, 3, 4);
    sumAll(1, 2, 3, 4, 5); 

    The rest parameter can be used alongside other defined inputs, but must always be the last one in the function’s definition.

    var sumAll2 = function (a, b, …otherInputs) {
        let sum = a + b;
        for(let i of otherInputs){
            sum += i;
        }
        return sum;
    }

    // This call is invalid, since b is undefined
    sumAll2(1);

    // These calls are valid
    sumAll2(1, 2);
    sumAll2(1, 2, 3);
    sumAll2(1, 2, 3, 4);
    sumAll2(1, 2, 3, 4, 5);
