What are Typescript Features?
- Object-oriented code for client-side and server-side development. Programmers gain access to interfaces, classes, inheritance, and modules, which allows them to hit the ground running during development.
- Strong typing or static typing. And, of course, TypeScript is meant to do primarily one thing, provide for optional static typing or strong typing. This makes it far easier for developers to deploy complex code faster.
What are the Typescript Components?
- The compiler. The compiler of TypeScript ensures that the script has been programmed correctly. Rather than finding errors upon actually running the code, programmers are able to find errors when the documents are compiled.
- Language services. This service provides some typical editor features such as suggestions and syntax highlighting, which further help developers start programming very quickly.
How to Install Typescript
TypeScript can be installed via NPM by running “NPM install typescript –save-dev.” It can also be installed with Visual Studio through Nuget through the Packages Manager Console or through the TypeScript Visual Extension. You can look up a video if you need to know more about how to install TypeScript.
Of course, TypeScript isn’t just a client-side language but also a server-side language. This is how to install TypeScript for development, but it will also need to be installed server-side if it is going to compile server-side code. This would need to be installed on the server itself by the server administrator.
What are Typescript Best Practices?
- Determine whether you need TypeScript. For fast, small deployments, you may not need to compile TypeScript code. TypeScript excels at larger programs.
- Let the compiler infer typing. Usually, the compiler itself is going to know the best typing for any given declaration. Let the compiler figure out typing for you rather than trying to manually type your objects. The compiler will figure out the most accurate specifications.
- Call functions with objects. Taking a parameter as an object makes more sense when using functions that have a lot of parameters of the same type, and it can produce code that is cleaner and easier to read.
- Don’t use bind. Bind is going to return “any” and there is no type check. Use an arrow function rather than using bind when writing in TypeScript.
