In ECMA-262, version 5.x (aka. ECMAScript 5 | ES5), there used to be a section 13.2 called Creating Function Objects
.
I have been searching through the latest version of the standard, ECMAScript 2017 (aka. ECMAScript 8 | ES8), but cannot find a similar description.
Section 14.1 in ES8 is called Function Definitions
, which is the same as section 13 in ES5. That's as far as I get.
Did they remove that whole piece? I thought it was a very helpful description of what actually happens when a new function is defined.
As there are many more kinds of function object and function syntaxes, this changed a bit.
In ES5 we had
10 Executable Code and Execution Contexts
…
10.4 Establishing an Execution Context
…
10.4.3 Entering Function Code
10.5 Declaration Binding Instantiation
10.6 Arguments Object
…
13 Function Definition
(syntax and evaluation of declarations and expressions)
13.1 Strict Mode Restrictions
13.2 Creating Function Objects
13.2.1 [[Call]]
13.2.2 [[Construct]]
13.2.3 The [[ThrowTypeError]] Function Object
In ES8 we have
9 Ordinary and Exotic Objects Behaviours
9.1 Ordinary Object Internal Methods and Internal Slots
9.2 ECMAScript Function Objects
9.2.1 [[Call]] ( thisArgument, argumentsList )
9.2.2 [[Construct]] ( argumentsList, newTarget )
9.2.3 FunctionAllocate ( functionPrototype, strict, functionKind )
9.2.4 FunctionInitialize ( F, kind, ParameterList, Body, Scope )
9.2.5 FunctionCreate ( kind, ParameterList, Body, Scope, Strict [ , prototype ] )
9.2.6 GeneratorFunctionCreate ( kind, ParameterList, Body, Scope, Strict )
