介绍

项目

o(1)的查找 哈希表没答出来,写deepClone的时候还用了hash

CSS 选择器优先级

JS 作用域和闭包 看题说输出


(function(){
var a = b = 3;
})();

console.log("a defined? " + (typeof a !== 'undefined'));
console.log("b defined? " + (typeof b !== 'undefined'));


let arrFunc = []

for(var i = 0; i < 4; i++){

    arrFunc.push(function(){

        return i

})

}

console.log(arrFunc[1]())
