Imagine this scenario:
function firstFunction() {
console.log("This is the first function")
}
secondFunction() {
thirdFunction() {
//call firstFunction inside thirdFunction
}
}
What is the way to invoke firstFunction from thirdFunction?
When functions are declared in the way you have demonstrated, they get hoisted to the top of the scope. This means that variable a is accessible globally and can be accessed by any code within the same global scope.
By implementing an arrow function on the parameter of c, I successfully resolved my issue.
The structure of your functions indicates that function c is nested within function b, impacting the scope during execution. To access function c, you must first call function b to reach it. Unfortunately, with your current code, directly accessing function c is not possible.
However, the provided code snippet demonstrates a way to properly call function c, which in turn calls function a:
function a() {
console.log("i am a")
}
function b() {
this.c = function() {
//call function a here
window.a();
}
return this;
}
b().c()During the development and testing phase on my local machine, everything was working as expected. However, once deployed to our UAT environment using Docker, I encountered some issues that are puzzling me: next() is not a function Another problem I'm ...
