How do you define a variable with a type in TypeScript?
Description : Use the syntax 'let variableName: type' to define a variable with a specific type.
Answer :
In TypeScript, you can define a variable with a type by using the colon(:) syntax. For example,'let age: number;' defines a variable 'age'of type 'number'. This allows TypeScript to check that only values of the correct type are assigned to this variable, providing additional type safety.
TypeScript is a statically typed language that builds on JavaScript by adding optional types. It allows developers to catch errors at compile time rather than runtime, which can help improve code quality and readability. TypeScript code is transpiled to JavaScript, making it compatible with existing JavaScript codebases and environments.
