getPatternProps 函数将返回一个包含我们模式属性的对象。 functiongetPatternProps() {letpatternProps = {start:{x:50,y:50,},numPoints:{min:5,max:12},space:{x:100,y:100},count:{x:12,y:6},fills:['#b8a9c9', '#98d1d6', '#fed8b...
let star_idx = x + props.count.x * y; let diff = props.numPoints.max - props.numPoints.min + 1; let morePoints = star_idx % diff; let numPoints = props.numPoints.min + morePoints; // determine star size let multiplier = (props.count.y - y) / props.count.y let outerRadius =...
function sum(x, y) { // antipattern: implied global result = x + y; return result; } 这段代码中,我们直接使用了result而没有事先声明它。这段代码是能够正常工作的,但在调用这个方法之后,会产生一个全局变量result,这会带来其他问题。 解决办法是,总是使用var来声明变量,下面代码就是改进了的sum(...
$(patsubst <pattern>,<replacement>,<text>) 根据此语法,上例里,就是将目录下所有 .c 后缀文件返回成同名 .o 的文件。在 patsubst 和 wildcard 在 QuickJS 的 makefile 里广泛使用,比如下面这段: ifdef CONFIG_LTO libquickjs.a: $(patsubst %.o, %.nolto.o, $(QJS_LIB_OBJS)) $(AR) rcs $@...
const assert = require('assert'); // antipattern it('should complete this test', function(done) { return new Promise(function(resolve) { assert.ok(true); resolve(); }).then(done); }); The above test will fail with Error: Resolution method is overspecified. Specify a callback *or...
设计模式(Design pattern)是一套被反复使用、多数人知晓的、经过分类编目的、代码设计经验的总结。使用设计模式是为了可重用代码、让代码更容易被他人理解、保证代码可靠性。毫无疑问,设计模式于己于他人于系统都是多赢的;设计模式使代码编写真正工程化;设计模...破解前端面试(80% 应聘者不及格系列):从 DOM 说起 ...

Why? Requiring operators at the beginning of the line keeps the operators aligned and follows a pattern similar to method chaining. This also improves readability by making it easier to visually follow complex logic. // bad if ((foo === 123 || bar === 'abc') && doesItLookGoodWhenItBec...
The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, ...
