[Bug]: iterableIsArray assumption with shadowing variable generates invalid code #16009
Description
💻
- Would you like to work on a fix?
How are you using Babel?
@babel/cli
Input code
Fn = (e) => {
return {
extract: () => {
const r = [];
for (const s of e) {
const e = s;
r.push(e);
}
return r;
},
};
};Configuration file name
babel.config.json
Configuration
{
"presets": [
"@babel/preset-env"
],
"assumptions": {
"iterableIsArray": true
}
}Current and expected behavior
current result:
"use strict";
Fn = function Fn(e) {
return {
extract: function extract() {
var r = [];
for (var _i2 = 0; _i2 < e.length; _i2++) {
var s = _e[_i2];
var _e = s;
r.push(_e);
}
return r;
}
};
};the _e reference in inner most block is not valid. should be
"use strict";
Fn = function Fn(e) {
return {
extract: function extract() {
var r = [];
for (var _i2 = 0; _i2 < e.length; _i2++) {
var s = e[_i2];
var _e = s;
r.push(_e);
}
return r;
}
};
