Older code often uses the function prototype to create "classes" out of functions. This upgrades those to ES6 class syntax.

Transforms constructor and methods
BEFORE
function MyClass() {
this.field = 1;
}
MyClass.prototype.update = function () {
this.field += 1;
};AFTER
class MyClass {
constructor() {
this.field = 1;
}
update() {
this.field += 1;
}
}Transforms and ignores empty constructor
BEFORE
function MyClass() {}
MyClass.prototype.update = function () {
this.field += 1;
};AFTER
class MyClass {
update() {
this.field += 1;
}
}Transforms persisting constructor arguments
BEFORE
function MyClass(arg1) {
someCall();
this.field = arg1;
}
MyClass.prototype.update = function () {
this.field += 1;
};AFTER
class MyClass {
constructor(arg1) {
someCall();
this.field = arg1;
}
update() {
this.field += 1;
}
}Does not transform non-prototype edited functions
JAVASCRIPT
function MyFunction() {
return '';
}
