May 16, 2017 · Lambdas are a short-hand syntax for declaring anonymous code structures. Closures are when a nested function (named or not) holds a reference to a variable from a function in an outer scope. That, in and of itself isn't really an issue.

Lambda expressions do for functions what object-oriented programing does for objects: It makes a function something you can assign to a variable. Lambda expressions are also sometimes called anonymous functions, lambda functions, and closures.

This is why I delve deep into the world of JavaScript lambda expressions in this comprehensive blog post. I'll explore their syntax and showcase practical examples to illustrate how they can be harnessed to write more concise and expressive code.

Syntax and Structure of JavaScript Lambda Functions The syntax of lambda functions in JavaScript is straightforward. The basic structure consists of the parameter list, an arrow function notation (=>), and the function body. For example: “` javascript const add = (a, b) => a + b; “`

Look at the definition: Lambda contains a transforming rule (substitution from a variable) and a syntax for declaring function. The generic usage of Lambda calculation is that any calculating function can be represented and calculated by lambda.
