call(), andapply(). If it sounds odd to you that a function might have its own methods - then remember that every function in JavaScript is an object. Readthisarticle for a refresher. You might also wonder what the difference is between a function and a method. I believe the descriptors...
Debouncing is a technique used to optimize application performance by reducing the rate at which functions are called. Some functions are expensive (could be using more memory, or could be using a lot of CPU time, or causing many database transactions), and we don’t want to call them too...
Before writing the code, let's first understand the idea. Note that there are many ways to debounce a function in JavaScript. But here is my approach. We define a function that we want to debounce. We set the function to be executed after a certain time. This specific time is an estim...
To understand callback functions you first have to understand regular functions. This might seen like a “duh” thing to say, but functions in Javascript are a bit odd. Functions in Javascript are actually objects. Specifically,they’reFunctionobjects created with theFunctionconstructor. AFunctionobj...

call() call([thisObj[, arg1[, arg2[, , argN]]]) 调用一个对象的方法,用另一个对象替换当前对象。 function callMe(arg1, arg2){ var s = ""; s += "this value: " + this; s += " "; for (i in callMe.arguments) { s += "arguments: " + callMe.argumentsi; s += " "; ...
[Javascript] this in Function Calls In most cases, the value of a function'sthisargument is determined by how the function is called. This lesson explains whatthisrefers to when we call plain function. Marius points out how functions behave differently in strict and non-strict mode."use ...
