let newArr = arr.map(item => ({
  'CountryName': item['CountryName'].trim(),
  'SourceName': item['SourceName'].trim(),
  'data': Object.keys(item).filter(key => key.startsWith('Y_')).map(year => parseFloat(item[year]) || 0)
}));
console.log(newArr);

I have one array of object. I want to map new array.

I want to create this array into another array of object like this

console.log(arr);

I want to convert this into

let newArr = [{
'CountryName': srilanka,
'SourceName': Nuclear,
'data': [0,0,0,0,0,0]
}];

I have tried to loop and map but it did not worked for me...

let createArrLineChart = [];
debugger;    
for (let index = 0; index < newArr ; index++) {
// const element = newArr [index];
// let createObj:any = {};
// createObj.Name = element.CountryName;
// createArrLineChart.push(createObj)
var result:any = newArr.map((person: any) => {
person.startsWith("Y_");
});
console.log(result)
console.log(newArr[index]);
}

How can I do this?

以下是您要翻译的内容：

  • 您尝试中的一些问题：
  • 循环条件 index < newArr 实际上应该是 index < newArr.length
  • 由于 person 是一个普通对象而不是字符串，调用 startsWith 不起作用。您需要迭代对象的键。
  • newArr 似乎是错误的引用，因为它将是从 arr 中获得的结果。

您可以通过解构来获取这两个名称，通过过滤器获取年份键。

例如：

const arr = [{...内容太长，省略部分...}];

const newArr = arr.map(({CountryName, SourceName, ...rest}) => ({
    CountryName,
    SourceName,
    data: Object.keys(rest).filter(key => key.startsWith("Y_")).map(key => +rest[key])
}));

console.log(newArr);

请注意，上述代码是对您提供的代码的翻译和修改。如果您有其他问题或需要进一步的帮助，请告诉我。

英文:

Some of the issues in your attempt:

  • The loop condition index < newArr should actually be index < newArr.length
  • As person is a plain object and not a string, calling startsWith on it will not work. You need to iterate the object's keys.
  • newArr seems the wrong reference, as that would be the result from arr.

You could get the two names via destructuring, and the year-keys via a filter.

For example:

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->

const arr = [{&quot;rn&quot;: &quot;1&quot;,&quot;EnergyParameterId&quot;: &quot;4&quot;,&quot;CountryId&quot;: &quot;1&quot;,&quot;CountryName&quot;: &quot;Bangladesh
