Description
This rule prohibits assigning variables to this.
Bad Practice
//Assigning a variable to this instead of properly using arrow lambdas may be a symptom of pre-ES6 practices or not managing scope well.
//Instead of storing a reference to this and using it inside a function () {:
const self = this;
setTimeout(function () {
self.doWork();
});
Recommended
// Use () => arrow lambdas, as they preserve this scope for you:
setTimeout(() => {
this.doWork();
});
