✨Meta Programming Guide.

You want to learn Meta-programming, or you don't know what Meta-programming is. In this post, I will a give a brief guide into learning the concept Meta programming is writing programs that treats other programs as data. It's derived from the word "meta," which refers to a self-referential, higher-order form of an object. Most libraries and development tools use Meta programming as a development concept. Meta programming is a common term for most modern programming languages. Though you may never have to use the concept in application code, it is a good way of understanding how libraries work under the hood. It can also be useful if you are building a framework for yourself or your team. Here are some things to note about meta programming though. 1) Different languages have very different ways of handling meta-programming. For example, Python's way of handling the concept type.prepare() is different from JavaScript's way of handling it new Proxy (). 2) Metaprogramming comes with performance overhead. it brings in a form of flexibility in some languages that are rather rigid by structure. For example, in Java, you can't set attributes for classes if the attributes are not declared with the class. With the Reflection API that's possible. Java's speed is as a result of its rigidity and Meta-programming compromises that. 3) They need a rather deep knowledge of how the language works. I mean knowledge deeper than syntax, like runtime execution process and context management. So, it's generally advised to learn it in your preferred language. 4) They are easier in Object Oriented Programming languages than in other programming paradigms. Meta-programming is always included with the concepts of Classes, Types and Objects. Libraries like Spring Boot, Svelte, Django, SQL-Alchemy all use meta programming in their codebases. Learning it will give you a significant advantage over other developers.

Meta programming is writing programs that treats other programs as data. It's derived from the word "meta," which refers to a self-referential, higher-order form of an object.

Most libraries and development tools use Meta programming as a development concept. Meta programming is a common term for most modern programming languages.

Though you may never have to use the concept in application code, it is a good way of understanding how libraries work under the hood. It can also be useful if you are building a framework for yourself or your team.

Here are some things to note about meta programming though.

1) Different languages have very different ways of handling meta-programming. For example, Python's way of handling the concept type.__prepare__() is different from JavaScript's way of handling it new Proxy ().

2) Metaprogramming comes with performance overhead. it brings in a form of flexibility in some languages that are rather rigid by structure.

For example, in Java, you can't set attributes for classes if the attributes are not declared with the class. With the Reflection API that's possible.

Java's speed is as a result of its rigidity and Meta-programming compromises that.

3) They need a rather deep knowledge of how the language works. I mean knowledge deeper than syntax, like runtime execution process and context management. So, it's generally advised to learn it in your preferred language.
