NAME
       qjs - QuickJS-NG JavaScript interpreter


SYNOPSIS
       qjs [OPTION]... [FILE [ARGUMENT]...]


DESCRIPTION
       QuickJS-NG is a small and embeddable JavaScript engine.  It aims to
       support the latest ECMAScript specification.

       The qjs executable runs the JavaScript interpreter.  It includes a
       simple standard library and REPL.


OPTIONS
       -c, --compile
              Compile FILE into a standalone executable, bundling the
              interpreter and the script.


       -C, --script
              Load FILE as a classic JavaScript script.  By default, qjs will
              try to detect if FILE is a JS script or an ES module.


       -d, --dump
              Dump memory usage statistics.


       -D FLAGS, --dump-flags=FLAGS
              Specify debug dump flags.  These can also be set through the
              QJS_DUMP_FLAGS environment variable.


       -e EXPR, --eval EXPR
              Evaluate EXPR and exit.


       -h, --help
              Print a help message and exit.


       -i, --interactive
              Enter interactive mode. This is the default if no FILE is
              provided.


       -I IFILE, --include IFILE
              Include an additional file.


       --memory-limit N
              Limit memory usage to N Kbytes.


       -m, --module
              Load FILE as an ECMAScript module.  By default, qjs will try to
              detect if FILE is a JS script or an ES module.


       --o OUTPUT, --out OUTPUT
              Output file name when creating a standalone executable with -c.


       --stack-size N
              Limit the stack size to N Kbytes.


       --std  Make 'std', 'os' and 'bjson' available to the script.


       -T, --trace
              Trace memory allocation.


       -v, --version
              Print version string and exit.


       -q, --quit
              Instantiate the interpreter and immediately exit.
