## TL;DR

Julia (Jeff Bezanson, Stefan Karpinski, Viral Shah, Alan Edelman, 2012, MIT) solves the 'two-language problem' — high-level syntax with C-like speed. Just-in-time (JIT) compilation via LLVM. Used for scientific computing, ML, finance, and HPC. Key packages: DifferentialEquations.jl, Flux.jl (ML).

## Core Explanation

Multiple dispatch: functions defined by combination of ALL argument types — core paradigm. No classes: structs + functions (functional paradigm). `@time` macro for performance measurement. GPU support: CUDA.jl for NVIDIA, AMDGPU.jl for AMD. High-level Python/Matlab-like syntax: `A * B` automatically optimizes. 1-indexed arrays (like Matlab/Mathematica/R).
