In computer programming, assembly language (alternatively assembler language [1] or symbolic machine code), [2] [3] [4] often referred to simply as assembly and commonly abbreviated as ASM or asm, is any low-level programming language with a very strong correspondence between the instructions in the language and the architecture's machine code instructions.

While Emscripten and similar compilers allow web developers to write new code, or port existing code, written in a high-level language such as C, C++, Go, and Rust to WebAssembly to achieve potentially higher, native-level execution performance in web browsers, this forces web developers accustomed to developing client-side web scripts and ...
x86 assembly language is a family of low-level programming languages that are used to produce object code for the x86 class of processors. These languages provide backward compatibility with CPUs dating back to the Intel 8008 microprocessor, introduced in April 1972.
Assembly language provides a direct map between the numerical machine code and a human-readable mnemonic. In assembly, numerical opcodes and operands are replaced with mnemonics and labels. For example, the x86 architecture has available the 0x90 opcode; it is represented as NOP in the assembly source code.
In the x86 assembly language, the JMP instruction performs an unconditional jump. Such an instruction transfers the flow of execution by changing the program counter.There are a number of different opcodes that perform a jump; depending on whether the processor is in real mode or protected mode, and an override instruction is used, the instructions may take 16-bit, 32-bit, or segment:offset ...
High-Level Assembly (HLA) is a language developed by Randall Hyde that allows the use of higher-level language constructs to aid both beginners and advanced assembly developers. It supports advanced data types and object-oriented programming .

A high-level assembler in computing is an assembler for assembly language that incorporate features found in a high-level programming language.. The earliest high-level assembler was probably Burroughs' Executive Systems Problem Oriented Language (ESPOL) in about 1960, which provided an ALGOL-like syntax around explicitly-specified Burroughs B5000 machine instructions.
