// Such an array can be in one of two modes: // - fast, backing storage is a FixedArray and length <= elements.length(); // Please note: push and pop can be used to grow and shrink the array. // - slow, backing storage is a HashTable with numbers as keys. class JSArray: ...
下面是 weblas 的简单示例：// create Matrices as arraysvar height_A = 1024, width_A = 1024, height_B = 1024, width_B = 1024;var A = new Float32Array(height_A * width_A);var B = new Float32Array(height_B * width_B);// fill A and B with sciencevar M = height_A, ...
We now have an array with 1,000,000 elements. Let's fill it with some data. if(turbojs){varfoo=turbojs.alloc(1e6);for(vari=0;i<1e6;i++)foo.data[i]=i;// print first five elementsconsole.log(foo.data.subarray(0,5));} ...
Since the number of arguments toCartesianProductis variable, it is sometimes helpful to give a single array with all arguments. But you cannotnew ctor.apply(null, args)this case. To mitigate that, you can use.from(). leta16=Array(16).fill('0123456789abcdef');it=CartesianProduct.from(a16...
3.1、应尽量使用文字语法创建数组(如果有必要,特殊情况除外,如:new Array(10).fill(true)) //badconst items =newArray();//goodconst items = []; 3.2、使用 spread(‘...’)操作符copy数组 //badconst len =items.length; const itemsCopy=[]; ...
Float32Array.prototype.fill( value[, start[, end]] ) Fills an array from a start index to an end index (non-inclusive) with a provided value. var arr = new Float32Array( 2 ); // Set all array elements to the same value: arr.fill( 2.0 ); var v = arr[ 0 ]; // returns 2....

Type:Array An array of numbers strictly greater than 0, where 1 means regular speed (100%), 0.5 means half-speed (50%), 2 means double-speed (200%), etc. If specified, Video.js displays a control (of classvjs-playback-rate) allowing the user to choose playback speed from among the...
