v7.0.0-beta.35

Update @babel/helper-wrap-function templates (#6984 )
This commit introduces 4 changes: 1) Function declarations are wrapped using function declarations. This has two advantages: - We can rely on native hoisting, instead of using _blockHoist - The function isn't wrapped until it is called. This avoids problems where `regeneratorRuntime.wrap` was called before that `babel-polyfill` was imported. Example: function fn() {} // becomes function fn() { return _fn.apply(this, arguments); } function _fn() { _fn = _wrapper(/* Original function ... */); return _fn.apply(this, arguments); } 2) Use a single template for both named and anonymous function expressions. They already had the same behavior, but the one used for named functions was a bit longer. 3) Use normal functions instead of arrow functions to wrap function expressions. 4) Generate a name based on the original one for wrapped functions (e.g. `foo` becomes `_foo` instead of `_ref`).

+## Hallelujah—In Praise of Babel
+
+I heard there was a clever trick  
+That rewrote all your JavaScript  
+But you don’t really care for magic, do you  
+Well it goes like this: the source, the dist  
+The ES five, the ES six  
+The sacred script transforming Hallelujah  
+
+Hallelujah, Hallelujah  
+Hallelujah, Hallelujah
+
+So I added all the shiny things  
+Classes, spreads and template strings  
+Through syntax sugared code I tried to woo you  
+Generators, const and let  
+I used them all without regret  
+And it’s a terse and a destructured Hallelujah  
+
+Hallelujah etc.
+
+Well my faith was strong but I needed proof  
+The standard was my source of truth  
+But TC39 meant nothing to you  
+So even though you weren’t impressed  
+I checked the build against the spec  
+And it’s a more-or-less compliant Hallelujah  
+
+Hallelujah etc.
+
+Now you say the build step’s too complex  
+And you claim no need for ES Next  
+Well I used to think that way before I knew you  
+But your code grows older with each line  
+It’s a joyless dirge on a withered vine  
+It’s a threnody for a bygone Hallelujah  
+
+Hallelujah etc.
+
+Yes I learned about the danger signs  
+How they’d polyfilled a thousand lines  
+The cost of using Maps and Symbols threw you  
+Still I disregarded common sense  
+Now my source is small but the build’s immense  
+And it’s a slow and unresponsive Hallelujah  
+
+Hallelujah etc.
+
+There was a time when they let me know  
+What’s really going on below  
+But now there’s only source maps there to school you  
+And debugging’s not a progress march  
+It’s a frenzied fumble in the dark  
+It’s a labyrinthine search for Hallelujah  
+
+Hallelujah etc.
+
+Well, maybe there’s a god up there  
+But all I ever got from prayers  
+Was broken builds and errors that would spook you  
+And that anguished cry you hear at night  
+Is the plugin I forgot to write  
+It’s a cold and it’s a broken Hallelujah  
+
+Hallelujah etc.

Nicolò Ribaudo	05b22d2597	Update `@babel/helper-wrap-function` templates (#6984 ) This commit introduces 4 changes: 1) Function declarations are wrapped using function declarations. This has two advantages: - We can rely on native hoisting, instead of using _blockHoist - The function isn't wrapped until it is called. This avoids problems where `regeneratorRuntime.wrap` was called before that `babel-polyfill` was imported. Example: function fn() {} // becomes function fn() { return _fn.apply(this, arguments); } function _fn() { _fn = _wrapper(/* Original function ... */); return _fn.apply(this, arguments); } 2) Use a single template for both named and anonymous function expressions. They already had the same behavior, but the one used for named functions was a bit longer. 3) Use normal functions instead of arrow functions to wrap function expressions. 4) Generate a name based on the original one for wrapped functions (e.g. `foo` becomes `_foo` instead of `_ref`).	2017-12-13 16:21:58 +01:00
