While working with Cypress, I noticed that using a while loop caused some issues. Instead of the while loop, I came up with this alternative solution:
const functionName = () => {
if ( a != b ) {
this.functionName();
} else {
cy.get(".selector").click()
}
};This block of code in TypeScript works really well, but 'this' is highlighted in red and shows the message: "Object is possibly 'undefined'."
Any suggestions on how to fix this error?
If you encounter a typescript error, consider utilizing the Non-null assertion operator
// When compiled with --strictNullChecks
function validateEntity(e?: Entity) {
// Throw an exception if e is null or not a valid entity
}
function processEntity(e?: Entity) {
validateEntity(e);
let s = e!.name; // Assert that e is non-null and access its name property
}

In this scenario, it's likely unnecessary to use the this. prefix since the function is defined within the current scope rather than as a class method.
