Introduction: Why TypeScript is Your Ticket to IT

TypeScript has firmly established itself as one of the most in-demand languages in web development. Large companies (Google, Microsoft, Airbnb) and startups are increasingly choosing it for their projects. For a beginner developer, knowledge of TypeScript is not just a plus, but often a mandatory requirement. In this article, we will look at how a beginner with no commercial experience can find their first job, create a resume, and prepare for an interview.

We won't say "learn it in 3 days" — that's unrealistic. Instead, we will give you a concrete action plan from A to Z.

1. What a Beginner TypeScript Developer Needs to Know

To qualify for a Junior TypeScript Developer position, you need to have a set of hard skills. Here is a minimum checklist:

Basic JavaScript (ES6+) — TypeScript is a superset; without understanding JS, you won't be able to write types meaningfully.
TypeScript Basics: types, interfaces, generics, enum, union/intersection types.
React or Angular — most junior vacancies involve working with a framework.
Git — at least basic commands: commit, push, pull, merge.
Understanding REST API — ability to work with fetch/axios.

An example of simple code that you should be able to explain:

interface User {    id: number;    name: string;    email?: string; // optional field}

function greet(user: User): string {    return `Hello, ${user.name}!`;}

const admin: User = { id: 1, name: "Alexey" };console.log(greet(admin)); // Hello, Alexey!

Note: using interface and optional fields is basic knowledge that is asked about in every interview.

1.1. Practical Projects for Your Portfolio

Without work experience, you need to show that you can apply your knowledge. Make 2-3 projects:

Todo App on React + TypeScript (with types for props and state).
Weather Widget with an external API (will demonstrate working with asynchrony and typing responses).
Small REST API on Node.js + Express + TypeScript (a plus if you use Prisma or TypeORM).

Upload the code for each project to GitHub with a clear README. Employers look at code quality, not the number of stars.

2. How to Create a Resume Without Work Experience

The main mistake beginners make is writing "No experience" in their resume or leaving the "Work Experience" section empty. There is a way out: use other sections.

2.1. Resume Structure for a Junior

Contact Information — email, phone, link to GitHub, LinkedIn (mandatory).
Objective — briefly: "Seeking a Junior TypeScript Developer position. I want to grow in the direction of frontend/full-stack development."
Technical Skills — list everything you know, but be honest. Example: TypeScript, React, Git, HTML/CSS, Node.js (basic).
Projects — describe 2-3 projects from your portfolio. For each, specify: name, tech stack, what you did, link to GitHub.
Education — if you have relevant education (university, courses), specify it. If not, it's okay; many developers are self-taught.
Additional — English proficiency (at least Intermediate level), participation in open-source, certificates.

Example of a project description in a resume:

Project: Weather AppTech Stack: React, TypeScript, OpenWeatherMap API, CSS ModulesDescription: SPA for displaying weather in any city. API response typing,error handling, search with debounce implemented. Code on GitHub: [link]
