Meaning of the ">=" Operator in JavaScript

The ">=" operator in JavaScript is used for comparing numbers and strings. It means "greater than or equal to."

Example

let num1 = 5;
let num2 = 10;

if (num1 >= num2) {
  // This condition will be false because num1 is not greater than or equal to num2
}

Arrow Function in JavaScript

The JavaScript code you provided also contains an arrow function, which is denoted by the => syntax. Arrow functions are a concise way to write function expressions.

promiseTargetFile(fpParams, aSkipPrompt, relatedURI).then(aDialogAccepted => {
  // Code to be executed when the promise is settled
}).then(null, Components.utils.reportError);

In this example, aDialogAccepted is a parameter of the arrow function. The arrow function returns an object that is passed to the .then() method.
