Array.prototype.find()是 JavaScript 中的一个数组方法,用于返回数组中满足提供的测试函数的第一个元素的值。否则返回undefined。 基础概念 该方法接收一个回调函数作为参数,这个回调函数会被数组的每个元素依次调用,直到找到一个使回调函数返回true的元素。回调函数本身接收三个参数: ...
JavaScript has relied on callbacks since forever. In web browsers, events are handled by passing references to (often anonymous) functions that act like callbacks. In Node.js, callbacks used to be the only way asynchronous elements of your code communicated with each other - up until promises w...

The subset of the font needed to render the glyphs will be embedded in the PDF. This is usually the mode you want to use with PDF canvases. SVG glyph does not cause <text> elements to be produced as one might expect (cairo bug). Rather, glyph will create a <defs> section with a...

NSArrayobjects or Swift arrays become JavaScript arrays and vice versa, with elements that JavaScriptCore recursively copies and converts. Objective-C blocks (or Swift closures with the@convention(block)attribute) become JavaScriptFunctionobjects, with parameter and return types that JavaScriptCore convert...
