A JavaScript interpreter from scratch, supporting ES5 syntax.
Clone and compile:
$ git clone [email protected]:zhuzilin/es.git
$ cd es
$ g++ es.cc -std=c++17 -I$(PWD) -O2 -Wall -Wextra -Wno-unused-parameter -o bin/es
Run:
$ echo "console.log('hello world!')" > hello_world.js
$ bin/es hello_world.js
"hello world!"
Use test/*.cc:
cmake -S . -B build
cmake --build build
cd build && ctest; cd ..Run the quickjs test:
sh quickjs-test.sh
The quickjs tests pass if there is no output.
I've learned a lot from Constellation/iv, V8 and thanks a lot for Annotated ECMAScript 5.1.
