aFalsey : will match if whatever value can be converted to a boolean false in javascriptSo for example :check(0).is(aFalsey); check(1).is(aTruthy); check('').is(aFalsey); check(true).is(aTruthy); check(true).is(aTrue);Will...
我们的源代码中有一个很常用的函数invariant，这个文档（https://github.com/zertosh/invariant#invariantcondition-message）很好地解释了它的功能：var invariant = require('invariant');invariant(someTruthyVal, 'This will not throw');// No errorsinvariant(someFalseyVal, 'This will throw an error with th...
useDataApi钩子返回[,doFetch],但doFetch实际上是setUrl,所以如果你想让它像预期的那样工作,你可以让url的初始值为null或falsey,并且只允许在url有效/真实的情况下在效果中进行提取。当你点击按钮时,那就是你setUrl的时候,那就是效果将允许fetchData发生的时候,因为那时url的值将被设置。 代码语言:javascript 复制...

@Devid - you could simplify to let a = Number('x') || 0; - Number('x') would return NaN, which is "falsey". Therefore, a would be assigned 0. Much cleaner and arguably (slightly) quicker than using the ternary statement and parsing twice. small hint: don't use new Number() ...
