CPP STL Lambdas Equivalents: Compare and Contrast

CPP STL Lambdas are a powerful feature introduced in C++11 that allow for defining anonymous functions inline, making it easier to write concise and functional-style code. Lambdas support closures (capturing variables by value or reference) and can be used wherever a function object or pointer is needed. Below is a detailed comparison of their equivalents across various programming languages.

Python

Equivalents: Python provides `lambda` for anonymous functions.
Key Features: Inline, single-expression functions used in functional constructs like `map`, `filter`, and `reduce`.
Strengths: Simple and widely used in functional programming.
Weaknesses: Limited to single expressions, unlike full-function lambdas in CPP.

PowerShell

Equivalents: Script blocks (`{}`) are used for inline anonymous functions.
Key Features: Inline blocks can be passed to cmdlets or invoked directly.
Strengths: Simple for scripting tasks.
Weaknesses: Limited flexibility and no advanced lambda features like captures.

Bash

Equivalents: No direct equivalent for lambdas; functions are used instead.
