In the question“What are the best (productivity-enhancing, well-designed, and concise, rather than just popular or time-tested) programming languages?” Assembly is ranked 61st while LiveScript is ranked 67th. The most important reason people chose Assembly is:
One of the best ways to learn how a computer actually works is to work your way up from lower level abstractions. Assembly, being only a level above machine code, is low enough level to make it clear how the computer is actually performing a computation, including code flow and loops, but high enough level to not be excessively tedious for the type of small projects that a student would do at the beginning of their first programming class. Use of an assembler with macros can stretch this even a bit further.
Question Ranking
Pros
Pro Low Level - it's how the computer works
One of the best ways to learn how a computer actually works is to work your way up from lower level abstractions. Assembly, being only a level above machine code, is low enough level to make it clear how the computer is actually performing a computation, including code flow and loops, but high enough level to not be excessively tedious for the type of small projects that a student would do at the beginning of their first programming class. Use of an assembler with macros can stretch this even a bit further.
Pro Naturally creates fast and small programs
Because of its natural syntax and low-level nature, assembly language programs are typically really small and fast.
Unlike other programming languages, in assembly language it is really hard to create a slow and over-bloated program.
Pro You must look into it if you really want to understand what computers do
There is no other way to understand a processor, so dig in.
Pro Useful for embedded systems
A curriculum that involves an embedded component, such as an Arduino or a Raspberry Pi, can encourage students by allowing them to immediately connect their work with 'real systems'. Assembly is the ideal language for getting started with and understanding these devices, and since Assembly can be called from C, the code will still be useful if students move on to C later in the program.
Pro Uniform syntax
Assembly language syntax is relatively uniform, and so there's less room for a student to get confused by obscure characters, or miss some meaning implied by structure, such as with scoping rules, or call-by-name/value/reference semantics. While there may be a lot of mnemonics to look up, most work involves only a very small subset of them.
Pro Designed for High-level functional code
LiveScript has terse syntax for common functional operations like map, and ships with a library, prelude.ls, with many of the functions most commonly used by functional programmers.
Pro Good amount of programmer flexibility
There's a huge range of features that can make common tasks faster.
Pro ECMA 6 Features
It is the declared goal of LiveScript’s creators to track ECMAScript 6. Hence, the language gives you ECMAScript 6 plus type annotations (which are optional).
LiveScript's module syntax is currently a bit behind the ECMAScript 6 specification (something that will be fixed eventually). It supports two module standards: CJS (Node.js) and AMD (RequireJS).
Pro Fixes coffeescript scoping issues
= is used to declare variables in the current scope, in order to redeclare variables of outer scope := is used. This way bugs are reduced.
Pro Supported by WebStorm and Visual Studio
Cons
Con Difficult learning curve
Starting off as a beginner with assembly language could prove very daunting. I suggest learning a high level language first (e.g. C) to get a good grasp of programming - especially dealing with bits, bytes, numbers, accessing memory with pointers (which is why I suggest C).
Then once that person is comfortable writing C (or whatever high level language) programs, they would find moving to assembler a little less of a "What the hell?!!!" experience.
Con Rarely a requirement or used in professional employment
(except for experts, which will outperform you in assembly language and execution speed on any day of the week, simply because they have full control of the processor.)
Con Not very portable
The instruction set may change depending on what CPU architecture is being used. Also, there will be some differences in implementations due to different assemblers being used, such as with changes in OS.
Con Language for those sadists that like pain
Not recommended as a first language. However, in small doses to show how higher level code is executed, can be of some value. Is also a language that will take a longer time to learn or finish projects with, so usually not for those who are in a hurry to get anything in particular done.
Con Hyperspecific syntax isn't a good first step to learning other modern languages
Con Strong functional lean
LiveScript is designed to be a high level functional language. For people who prefer a more imperative approach it can be hard to get used to.
Con Compiles to unreadable javascript
