To Reproduce
This code:
const o = {
func() {
console.log('This is a function');
},
func2() {
const bound = () => this.func();
return {
hu() {
console.log('This is a nested function');
bound();
},
};
},
};
is compiled wrong in export mode.
Current vs. Expected behavior
This code:
const o = {
func() {
console.log('This is a function');
},
func2() {
const bound = () => this.func();
return {
hu() {
console.log('This is a nested function');
bound();
},
};
},
};
is compiled to in version 15.4.2:
let e = {
func() {
console.log('This is a function');
},
func2: () => ({
hu() {
console.log('This is a nested function'), this.func();
},
}),
};
which is wrong.
Version 15.3.5 compiles:
let e = {
func() {
console.log('This is a function');
},
func2() {
let e = () => this.func();
return {
hu() {
console.log('This is a nested function'), e();
},
};
},
};
which is correct.
