The for...of statement is used to loop over iterable objects like arrays, strings, Map, Set and NodeList objects and generators. On each iteration, we check if the current element is not equal to the first array element. If the condition is met, we set the areEqual variable to false ...
A data structure (a.k.a. acollection) isan object that keeps track of other objects. Lists are the most commonly used data structure in Python. Anytime you need tostore and manipulate an ordered collectionof things, you should consider using a list. ...
为什么我用sum得到一个TypeError“'float'object is not iterable”? 因为chime_cra和chime_cdec是float,所以不需要使用sum来求和。您可以执行sum([chime_cra, chime_cdec]),这是sum的一个iterable,它不会在第一个循环中抱怨。 虽然没有必要,但您应该只使用chime_cra + chime_cdec。 此外,这行代码稍后会导致另...
In JavaScript, arguments is not an array, it is an “array-like object” 😅. Because it’s an iterable, you can use a for loop to iterate over it, but if you want to use array methods like forEach, you need to convert it to an array first. There are a few different ways to...

In the class or function game, we take something that we "call" (using parentheses: ()) and we guess whether it's a class or a function.For example:We can call zip with a couple iterables and we get another iterable back, so is zip a class or a function? When we call len, ...
Another use for iterators that’s interesting and that I incorporated with my projects is creating a simple utility method to convert plain old JavaScript objects into iterables: 123456789101112131415161718 constgetIterableMap=(map)=>{constkeys=Object.keys(map)letnextIndex=0;constiterable={...map}ite...
as well as any Map or Array object to foreach as collection parameter. When using an Iterable or Array, index will be the number of current iteration and value item will be the element retrieved in this iteration. When using a Map (or Collection of Map.Entry objects), index will be the...
For the C# developers: This library looks A LOT like Linq To Objects, the only difference being that the method names are more conventional ('filter' instead of 'Where', etc.). For the javascript developers: This library looks A LOT like lodash, underscore, ......
