this is not preserved when extracted to function in module scope #39931
Description
TypeScript Version: 3.9.6
Search Terms: extract to function, this
Code
function test(this: any, foo: string) {
console.log(this.name);
console.log(foo);
}Select these two console.log and extract them to function in module scope.
Expected behavior:
this should be passed to newFunction
function test(this: any, foo: string) {
newFunction(this, foo);
}
function newFunction(context: any, foo: string) {
console.log(context.name);
console.log(foo);
}Actual behavior:
this in newFunction is undefined now.
function test(this: any, foo: string) {
newFunction(foo);
}
function newFunction(foo: string) {
console.log(this.name);
console.log(foo);

Seems Refactoring is not supported on TypeScript Playground.
