TypeScript is a language that enables writing better code for large and complex projects. Explore What TypeScript is and its types through this blog.
TypeScript also has language features that aren’t part of JavaScript. The most prominent feature unique to TypeScript—the one that gave TypeScript its name—is, as noted, strong typing: a TypeScript variable is associated with atype, like a string, number, or boolean, that...

With TypeScript, when a variable is assigned a new value, IDEs and validation tools can quickly check that change against tens of thousands of lines of code. The same type of check is difficult to perform with JavaScript. This increases the risk of error when extending, updating and troublesh...
Entering the programming environment, a person can hear the question: “What is TypeScript?” TypeScript is a programming language that is a further development of JavaScript and adds static typing to the projects. This feature helps the developers to detect the errors at the initial stages and...
JavaScript functions can also be invoked with the new operator. TypeScript refers to these as constructors because they usually create a new object. You can write a construct signature by adding the new keyword in front of a call signature: ...
This code above will output “1020”, a concatenation of number and string. This is not the expected output — meaning this can affect your code. The downside with JavaScript is that it will throw no error. You can fix this with TypeScript by specifying the types of each variable:...
TypeScript现在支持对ES6生成器具有本机支持的引擎的异步功能,例如Node v4及更高版本。异步函数的前缀是async关键字; await暂停执行,直到完成异步函数返回许诺并解开Promise返回的值。 例 在以下示例中,每个输入元素将以400毫秒的延迟一次打印出一个: 代码语言:javascript 复制 "use strict"; // printDelayed is a ...
Today, TypeScript is being used to build large open-source projects such as Angular.TypeScript was developed by Microsoft for the developers who want to build scalable applications in JavaScript and bring their knowledge and experience of structured and modern programming languages such as C# and ...
TypeScript gives you some additional features and types that let you do more with JavaScript. Tuple A tuple is a special array that you declare with a fixed number of elements. These elements can have different types, but the tuple must stick to the types in the order that you declare. ...
