This JavaScript tutorial explains how to use the math function called sqrt() with syntax and examples. In JavaScript, sqrt() is a function that is used to return the square root of a number.
* @param {number} x * @return {number}*/varmySqrt =function(x) {if(x<4)returnx==0 ? 0:1;varres=2*mySqrt(x/4)if((res+1)*(res+1)<=x && (res+1)*(res+1)>=0)returnres+1;returnres; };
每一个函数表示为一个对象,是Function的一个实例,Function对象提供一个内部属性[[scope]]该属性仅js引擎读取(题外话:想起来css的scoped属性,在vue组件中使用时,改样式文件只作用于该组件)[[scope]]包含一个函数被创建的作用域中对象的集合,这个集合就是函数的作用域链。当执行环境创建时,作用域链初始化为[[scope...
