The examples of callback function you gave are all called higher order function instead these functions accept callbacks as an argument.

Hi bro, I have a question/s
Is there any possible way to get front-end intern (do they exist? or are they any company offering them?) and how to find them ?
and how to make a strong front-end intern resume

[JohnSnow-giiv]

Is it possible to make an internal transition from frontend to backend or full stack or vice versa or change tech stack while working inside FAANG companies or startups.

[rajatawasthi]

Gratitude for your kindness and efforts

[vishalzinjade]

Very Nice Video !!
In last question, I guess one point is missing.
In arrow Function, hoisting doesn't work (It only works for regular function).

For example:
This will work:
console.log(addNum(5, 6))
function addNum(a, b) {
return a + b
}

But This one will not:
console.log(add(5, 6))
const add = (a, b) => {
return a + b
}

Please correct me.

[kamkhohao]
