How statistics are calculated
We count how many offers each candidate received and for what salary. For example, if a DAO/dApps developer with TypeScript with a salary of $4,500 received 10 offers, then we would count him 10 times. If there were no offers, then he would not get into the statistics either.
The graph column is the total number of offers. This is not the number of vacancies, but an indicator of the level of demand. The more offers there are, the more companies try to hire such a specialist. 5k+ includes candidates with salaries >= $5,000 and < $5,500.
Median Salary Expectation – the weighted average of the market offer in the selected specialization, that is, the most frequent job offers for the selected specialization received by candidates. We do not count accepted or rejected offers.

Where is TypeScript used?
Angular's BFF
- Angular developers get all giddy about TypeScript; it's like peanut butter to Angular's jelly. Their tight coupling makes single-page app creation a sweet, sweet symphony.
Node's New Pajamas
- In the Node.js playground, TypeScript is the new cool kid. It's like wrapping your back-end in a snuggie of strong typing, making bugs quake in their boots.
React's Type-Savvy Sidekick
- React has a buddy that ensures its components play nice. TypeScript is like the hall monitor, making sure all props have a hall pass before they enter the component classroom.
Big Bad Codebases
- Larger-than-life codebases are tamed by TypeScript's mighty sword of types. Like a coding superhero, it brings order to chaos and keeps villainous runtime errors at bay.
TypeScript Alternatives
Flow
Flow is a static type checker for JavaScript developed by Facebook. It introduces static typing to improve code quality in JavaScript applications.
// Flow example
// @flow
function square(n: number): number {
return n * n;
}
- Statically types JavaScript for improved error detection.
- Integrates with IDEs for real-time feedback.
- Gradual typing allows incremental adoption.
- Support for generics and complex types.
- Tighter integration with the Babel ecosystem.
- Less community support compared to TypeScript.
- Can be more complex to configure.
- The project is less actively maintained.
Dart
Dart is a scalable language optimized for building web, server, and mobile apps, offering a sound type system similar to TypeScript.
// Dart example
int square(int n) {
return n * n;
}
- Offers a complete ecosystem with its own VM.
- Strongly typed with rich standard library.
- Used in Flutter framework for app development.
- Less JavaScript interoperability compared to TypeScript.
- Community and resources not as vast as TypeScript.
- Ecosystem is more niche and less universal.
CoffeeScript
CoffeeScript is a language that compiles into JavaScript, providing syntactic sugar to enhance JavaScript readability and brevity.
# CoffeeScript example
square = (n) -> n * n
- Simpler syntax leads to more concise code.
- Reduces the boilerplate of JavaScript.
- Has influenced many JavaScript features.
- Lack of native type checking.
- Additional build step complicates the pipeline.
- Declining in popularity due to modern JavaScript.
Quick Facts about TypeScript
Launched by a Tech Giant With a Twist
Imagine Microsoft putting on a wizard's hat in 2012 and—abracadabra!—TypeScript was conjured into existence. Crafted by the coding Gandalf, Anders Hejlsberg (who’s also the father of C#), this nifty tool swooped in with the promise of taming the wild JavaScript dragons.
From Vanilla to Spicy JavaScript
TypeScript is like JavaScript who went to a private school and got extra etiquette lessons. It's JavaScript plus the superpower of types, giving developers the 'spidey-sense' to catch bugs in their web...code. It's all about boosting productivity and reducing the facepalm moments.
function greet(person: string, date: Date) {
console.log(`Hello ${person}, today is ${date.toDateString()}!`);
}
greet("Brendan Eich", new Date());
Versioning the Unversionable
Remember the time when we had to rely on coffee-stained release notes? TypeScript said 'no more!', with versions popping up more frequently than pop-up ads. Since 2012, the TypeScript landscape has evolved with versions bringing new shiny features faster than a developer's deadline.
What is the difference between Junior, Middle, Senior and Expert TypeScript developer?
Seniority Name | Years of Experience | Average Salary (USD/year) | Responsibilities & Activities | Quality-wise |
---|---|---|---|---|
Junior Developer | 0-2 | 50,000 - 70,000 |
| Requires close supervision |
Middle Developer | 2-5 | 70,000 - 100,000 |
| Requires moderate oversight |
Senior Developer | 5-10 | 100,000 - 130,000 |
| Self-sufficient and sets standards |
Expert/Team Lead | 10+ | 130,000 - 160,000+ |
| Ensures team delivers high-quality work |

template: 'Hello World!
'
})
export class HelloWorldComponent {}React with TypeScript
Ever wanted to sprinkle TypeScript magic dust on your React components? It's like peanut butter and jelly – better together. React's dynamic UIs get a boost with TypeScript's static bliss.

TypeORM makes dealing with databases feel like a walk in the park while on a unicorn – that is, if the unicorn understood object-relational mapping and had a knack for TypeScript.
import { Entity, PrimaryGeneratedColumn, Column } from "typeorm";
@Entity()
export class User {
@PrimaryGeneratedColumn()
id: number;
@Column()
firstName: string;
@Column()
lastName: string;
}TSLint/ESLint
Consider TSLint and ESLint the hall monitors of your TypeScript code. They'll keep you in line, although TSLint might be retiring soon, giving way for ESLint to rule the school.
// ESLint example with TypeScript
{
"extends": [
"eslint:recommended",
"plugin:@typescript-eslint/recommended"
]
}Jest with TypeScript
Because even your code needs a health checkup, Jest steps in to test your TypeScript. It's like having a personal fitness trainer for your functions and classes.
import { sum } from './sum';
test('adds 1 + 2 to equal 3', () => {
expect(sum(1, 2)).toBe(3);
});Prettier with TypeScript
