Too bad you had to use 'apply'. You made the lesson harder and confusing at that point. A lesson should be only about the subject you are trying to clarify, otherwise you break the flow of learning.
This is good, really good
Hi can you please provide a tutorial for writing js array coding technique like reversing given string , metrics , sorting with basic for loop instead of inbuilt methods something more like this ..
Nice video. I don't know why you show advanced techniques, then use a crappy for loop when you could use forEach.. 🙂
I'm just so glad I'm not the only one that thought of this pun 😅
It was actually invented by Moses Schönfinkel, but Shonfinkelling doesn't have the same ring to it eh? Haskell Curry actually credits Schonfinkel for what is now known as Currying. 🙂
I like your most of video even Udemy also
You are the man. Thank you.
best lecture
In the spiceUp function , you used fn.apply(this, n.concat(m)). Why can not we directly return fn(n.concat(m)) ? By the way it gives me the wrong result, but I don't know how ? Could you explain me that ?
9:47 can anyone explain why we need to call fn.bind.apply in line 11? as far as I see, in function avg (which will later be passed as 'fn' in line9), there's no use of 'this' keyword. So what's the point of 'apply'?
How to call super in an instance of sub constructor and an instance of sub constructor cannot access method declared inside main parent constructor, please see below
let Mammal = function (name, legs) {
this.name = name;
this.legs = legs;
this.getDetails = function () {
return `${this.name} walks with ${this.legs} legs`;
};
};
let Human = function (name, legs) {
Mammal.call(name, legs);
};
Human.prototype = Object.create(Mammal.prototype);
let ravi = new Human("Ravi", 2);
console.log(ravi.getDetails())
// here it is giving error and I want to call super in ravi instance.
how can I do that, please suggest
Sir, How many years of experience do u have in js sir
Very good explanation, I am getting laughing for every Js topic you are comparing it with real world scenario s😆😆😆😆😆😆, it's easy to understand we never forget the syntax and topic
Array.prototype.avarage=function(){
var total=0;
for(var i=0;i<this.length;i++){
total=total+this[i]
}
return total/this.length
}
let a=[1,2,3,4,5].avarage ()
console.log(a)
You are one of my JavaScript guru
Just watching this video again after a long time
classic techsith! Thanks
Finally i understand. Thank you!
i like curry, especially with pasta. but to use with js is much more tastier 🙂
Even if you don't use apply, I think it will work
Nice tutorial. Had one suggestion at 5.56. Since you are using ES6 feature, you could have used to reduce function here to avoid confusion. 🙂
@techsith, really like your videos,Thanks. there is one question about function currying, what is currying: the example at https://jsfiddle.net/jspatel/a0g7w08s seems to be partial application instead of function currying according to https://medium.com/javascript-scene/curry-or-partial-application-8150044c78b8
Thank you, this is really helpful.
you accent is really good man! great lecture too!!
very helpful tutorial …can we make like map functionality using currying ??
Thank you so much Hemil! Another great video. Please keep it up, you are so good at this!
I have learned a lot in this video. And the explanation is great.
hey @techsith, really love the videos.
Would appreciate if you could leave the links to jsfiddle or whatever external sources you want viewers to visit in the video description. Thanks and keep up the awesome work!!
Nice
How is this different from function chaining?
The second example is too complicated.
Hi Sir , could you please one example and use case for partial function in javascript , this question was asked in one interview.
Your video is really helpful and much easier to understand and thanks for that. Can you please let me know if this is also called a nested function. 🙂
Thanks.
it's quite confusing
The video thumbnails on this channel are unmatched
"You just use two numbers' average and it is very useful" – you said at 9:17 during this clip. What I don't understand about it is, we are never taking the average of the numbers that we already have. What we are doing is just concatenating arrays and make a big array and sending it to the function. How does it actually improve the performance. According to what I understood, it will run for the same time as you will run it by calling the function directly and passing on all the numbers. We are just holding the numbers in the closure and not the average of those. If we would have utilized the average from the numbers we have, it would have improved the performance. Am I stating it right? Can you help me understand?
If we have average in closure and utilize it, will it be better way of doing it.
Merci 🙂
AVG(4,5,6) is 5, and NOT 3.5 …
var curryIt = function(uncurried) {
var parameters = Array.prototype.slice.call(arguments, 1);
return function() {
return uncurried.apply(this, parameters.concat(
Array.prototype.slice.call(arguments, 0)
));
};
};
i didnt understand how it will get arguments
i'm a little bit confusing here. can you explain why you use "this" as a context in fn.apply() in spiceUp function?
Hi Patel,
Good to see all of your videos and they are very helpful. Your way of explaining is great!.
I am a wordpress / drupal developer wanted to shift to UI developer job as there is no much scope in my current domain.
I need some guidance to how to prepare javascript( it is like very big ocean).
Please add links in video description – that would be so much easier 😛
