What is a .JSX file?
JSX is a JavaScript source file containing React markup.
- Did you know
- JSX was introduced by Facebook alongside React in 2013.
- JSX lets you write HTML-like markup directly inside JavaScript, which React turns into createElement calls.
- Because browsers cannot read JSX, a tool such as Babel must transpile it into plain JavaScript first.
- Formally JSX is an XML-like syntax extension to ECMAScript with no built-in meaning of its own.
- Though tied to React in most people’s minds, JSX is a general syntax that other frameworks also adopt.
- What Analyser shows you
- Preview and inspect HTML, CSS, JavaScript, TypeScript, JSON, YAML, XML and Markdown source files, plus Windows scripts. TypeScript (TS, MTS, and .d.ts declaration files) gets a structure readout beside the source: the modules it imports (packages against local files, and which are type-only), the names it exports, what it declares - interfaces, type aliases, enums, classes, functions - a code/comment/blank line breakdown, and how often it steps around the type system with any, as casts, non-null assertions and @ts- suppressions. PowerShell (PS1, PSM1, PSD1) is read for its comment-based help synopsis, #Requires directives, function and parameter counts, CmdletBinding and Authenticode signing; batch/command scripts (BAT, CMD) for the echo state, labels, variables set and the external tools they invoke.
- Open a .JSX file
- Drag a .JSX file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
