Understand Abstract Syntax Trees - ASTs - in Practical and Useful Ways for Frontend Developers

[@nightwolf4343]

Usually I don't write comments for the videos, but this one is really helpful. So I would like to tell: Thank you for this!

[@newlinedotco]

Glad it was helpful!

I'm learning how to build compilers, and I was a bit lost at the subject of context-free grammars and ASTs, thanks for helping to clear that up!

[@ayush612]

Thank you sir for creating this unique video and in such depth ... Thank you and such an awesome presentation and quality!

[@newlinedotco]

You are welcome! Thanks for the kind words. We are glad you enjoyed this.

I am building a website editor. Any change in blocks data structure forces me to change the all templates data by hand. Thats why i am researching how AST works and how to build for my application. You began to the video with examples that exactly fit my situation

Great video. Learning this for GraphQL introspection parsing of nested fields and arguments.

22:07
const rootNode = parse(code).program.body[0].expression;
function traverse(node) {
if (!node) {
return;
}
if (node.type === "NumericLiteral") {
console.log(node.value);
}
if (node.left) {
traverse(node.left);
}
if (node.right) {
traverse(node.right);
}
}
traverse(rootNode);

How can I generate AST for C source code using C++ language? Please suggest me something.

[@newlinedotco]

This course was produced for JavaScript, but the theory/principles should carry to most other languages/tools. Our Discord server is a great resource to connect with others. You can join us here: discord.com/invite/D88ppSb

[@easycomputerscience69]

Can any one tell AST for java programs

[@newlinedotco]

This course is aimed at JavaScript, but the theory/principles should carry to most other languages/tools. With that focus, I don't have a specific tool recommendation but maybe google/stack overflow could help point you toward the right tools.
