In the code above, we break downarrinto smaller chunks of size3, by iterating through the array and slicing it everychunkSize. In the last iteration, there'll be only one element (10) left, which will have to make up its own chunk. ...
* * If you want to process the data in chunks as they arrive, specify a * function as the third argument. The chunks will be passed, as Uint8Array * objects, to this processChunk callback. * * streamBody() returns a Promise that resolves to a string. If a processChunk * callback...
let primes = [2, 3, 5, 7]; // An array of 4 values, delimited with [ and ]. primes[0] // => 2: the first element (index 0) of the array. primes.length // => 4: how many elements in the array. primes[primes.length-1] // => 7: the last element of the array. prim...
* bytes, and then the plaintext is possibly broken up into chunks. * * Note that, for padding with zeros, this routinewas altered by Rob Saunders * (rob@robsaunders.net). The new routine pads the string after it has been * converted to an array. This fixes an incompatibility with...

例如,我们传递给Array.prototype.map的函数不知道集合或如何操作它们。所有它知道的是如何操作一个价值。因此,它可以在单个值和集合的上下文中重用。 Function composition功能组成 Function composition is the combination of simple functions to build more complicated ones. Given two functions f and g, compose(f...
当您想要跳出不是最近的循环或switch的语句时,您需要带标签的break语句。以下代码演示了: let matrix = getData(); // Get a 2D array of numbers from somewhere // Now sum all the numbers in the matrix. let sum = 0, success = false; // Start with a labeled statement that we can break out...
