nodejs function syntax in module.export

Question

consider the following:

let y = doSomething(){ //doesn't work
    console.log('sdf')
}

let y = function doSomething(){ //works
    console.log('sdf')
}



module.exports = {
    getAll(){

    }
}

I had never seen this sort of function(inside the module.exports) is it a call or definition? It differs in that it doesn't have a keyword function, yet it's exported. What is it called? Does it have a specific name, most importantly, what are we actually doing in here? Please leave me a link to finding out more on this sort of definition if possible.

let y = function doSomething() {} called Function expressions

a name can be provided with a function expression. Providing a name allows the function to refer to itself, and also makes it easier to identify the function in a debugger's stack traces:

module.exports = {
  getAll(){}
}

It exports an anonymous object which has a getAll() method. It's called Method definitions
