Words within a name should start with a capital letter or an underscore. Select this checkbox to have WebStorm discern separate words within CamelHump names. If this checkbox is selected, then, on typing the closing curly brace, the enclosed code block is reformatted automatically if the formatting of this code block does not match the selected code style. Select this checkbox to have WebStorm automatically add a closing single or double quote for each typed opening single or double quote, respectively. ![]() Select this checkbox to have WebStorm automatically add a closing bracket for each typed opening bracket, respectively. When this checkbox is selected, on pressing End in an empty line, the caret is positioned with the indent, which WebStorm assumes to be reasonable in the current code point (indentation is based on the current Code Style Settings). Pressing Home subsequently moves the caret from the Smart Home position to the first column and back.Įnd on blank line moves caret to indent position When this checkbox is selected, on pressing Home, the caret is positioned at the first non-whitespace character of the current line. The default tsconfig.Home moves caret to first non-whitespace character Most developers add this file to their root directory. In WebStorm, add a tsconfig.json file by choosing File – New tsconfig.json File from the menu. ![]() The tsconfig.json file is a JSON file that tells the TypeScript compiler how to compile TypeScript to JavaScript. When you’re ready to start writing TypeScript code, add a tsconfig.json file (TypeScript configuration file) to the project. You can use it in any WebStorm project, including built-in project templates using JavaScript frameworks or existing projects. You don’t need to do anything to use TypeScript with WebStorm. TypeScript makes writing JavaScript apps quite easy because of these new programming features! Install and Configure TypeScript Finally, TypeScript has many syntactical enhancements and features from ECMAScript even before they’re standardized. It also performs module resolution and has the notion of namespaces, so you can more easily organize code. In addition to data types, TypeScript, like JavaScript, is object-oriented, so you can create models that mirror data stores or objects in the real world. TypeScript offers a full type system, since types are important to create correct code. This might sound easy, and it is – an easy way to get into trouble! This is especially true if some data is accepted from an input source that doesn’t match the expected type. ![]() Developers are free to change the data type of variables during a program’s execution. ![]() While JavaScript does contain a few primitive types, its type system is loosely typed, and types are inferred by their usage. Types are at the heart of TypeScript, and it performs type checking when compiling to JavaScript. TypeScript is a superset of JavaScript that contains features that make it easier to write and maintain than standard JavaScript. Rachel Appel TypeScript Language Overview
