Javascript 更改数组格式

如何更改此Javascript数组格式：

var sample_data = ["af","16.63","al","11.58","dz","158.97"];

要更改此对象格式，请执行以下操作：

var sample_data = {"af":"16.63","al":"11.58","dz":"158.97"};

它的代码如下所示

var sample_data = ["af","16.63","al","11.58","dz","158.97"];
var tmp = sample_data;
sample_data = {};
for (var i = 0; i < tmp.length / 2; i++) 
    sample_data[tmp[i * 2]] = tmp[i * 2 + 1];

var d={}；//临时物品
对于（变量i=0；i

也可以使用Array.shift执行此操作。不知道它与其他方法相比速度如何

var sample_data = ["af","16.63","al","11.58","dz","158.97"]; // source

var data = sample_data.slice(); // clone the data

sample_data = {};

while (data.length > 1) {
    sample_data[data.shift()] = data.shift() || null;
}

语言是什么？如果是JavaScript，则在第一个代码段中存在语法错误。它必须是

var-sample_data=[“af”、“16.63”、“al”、“11.58”、“dz”、“158.97”]语言？？？添加语言/技术标记。我将括号类型更改为[]
var d = {}; // a temporary object
for (var i = 0; i < sample_data.length; i += 2) {
    // iterate over sample_data with a step width of 2
    // and set the the data in the temp. object
    d[sample_data[i]] = sample_data[i+1];
}
sample_data = d;

var sample_data = ["af","16.63","al","11.58","dz","158.97"]; // source

var data = sample_data.slice(); // clone the data

sample_data = {};

while (data.length > 1) {
    sample_data[data.shift()] = data.shift() || null;
}
