Enhance Your Understanding with TypeScript Programming Concept Cards for quick learning
A superset of JavaScript that adds static typing and other features to help developers build large-scale applications.
The different types of values that can be assigned to variables in TypeScript, such as number, string, boolean, etc.
Containers for storing data values, which can be declared using the 'let' or 'const' keyword in TypeScript.
Reusable blocks of code that perform a specific task. In TypeScript, functions can have parameter types and return types.
Blueprints for creating objects that encapsulate data and behavior. Classes in TypeScript support inheritance and interfaces.
Instances of classes that hold their own data and have access to the methods defined in the class.
Organizational units of code that can be imported and exported to create a modular and maintainable TypeScript application.
Logical containers that help organize code and prevent naming conflicts by providing a scope for identifiers.
Structural contracts that define the shape of an object. TypeScript interfaces can be used for type checking and code documentation.
A way to create reusable components that can work with multiple types. Generics in TypeScript enable type parameterization.
A special kind of declaration that can be attached to classes, methods, properties, or parameters to modify their behavior.
The ability of TypeScript to automatically determine the type of a variable based on its initialization value.
Techniques for handling and reporting errors in TypeScript, such as try-catch blocks and throwing custom exceptions.
A programming paradigm that allows tasks to run concurrently and asynchronously. TypeScript provides async/await syntax for handling asynchronous operations.
The tool that converts TypeScript code into JavaScript code, enabling it to run in any JavaScript environment.
Strategies and tools for identifying and fixing errors in TypeScript code, such as using breakpoints and console.log statements.
Guidelines and recommendations for writing clean, efficient, and maintainable TypeScript code.
A concise syntax for writing functions in TypeScript, using the '=>' arrow operator.
A way to tell the TypeScript compiler that you know more about the type of a value than it does, allowing you to perform certain operations.
Conditional statements that narrow down the type of a value within a block of code, based on a type predicate.
A feature in TypeScript that allows you to safely access properties or call methods on an object that may be null or undefined.
A logical operator in TypeScript that returns the right-hand side operand if the left-hand side operand is null or undefined.
An array-like structure in TypeScript that allows you to specify the types of each element, with a fixed number of elements.
A way to create custom names for existing types in TypeScript, improving code readability and maintainability.
A way to combine multiple types into a single type in TypeScript, representing objects that have all the properties of each constituent type.
A way to specify that a value can have one of several types in TypeScript, using the '|' operator.
Functions that return a type predicate, which is a boolean value indicating whether a value satisfies a certain type.
The ability of TypeScript to inspect and manipulate the types of variables and other entities at runtime.
The rules that determine whether one type can be assigned to another type in TypeScript, based on their structure.
A way to obtain the type of a variable or property in TypeScript, using the 'typeof' operator.
The process of reducing the type of a value within a block of code, based on certain conditions or operations.
The process of increasing the type of a value within a block of code, based on certain conditions or operations.
Explicitly specifying the type of a variable or function parameter in TypeScript, using the ':' syntax.
A way to tell the TypeScript compiler that you know more about the type of a value than it does, allowing you to perform certain operations.
