我有一个对象数组，我想创建一个单独的对象，如果有一个公共密钥，它将在该密钥下创建一个新数组。比方说，我有以下数组：
[{
"Steering": ["Steering Type : EPAS with Pull Drift Compensation technology"],
"Power \u0026 Performance": ["1.5L Petrol Ti-VCT MT : ", "1.5L Petrol Ti-VCT AT : ", "1.0L Petrol Ecoboost MT : ", "1.5L Diesel DV5 MT : "],
"Wheels and Tyres": ["Tyres : 195 / 65 R15", "Wheels in inch : 15\" Steel Wheels"],
}, {
"INSTRUMENTATION": ["Tachometer : ", "Door Ajar Indicator : ", "Low Fuel Warning Lamp : ", "Distance To Empty (DTE) Display : ", "Headlamp on Key-off warning : "],
"TYRES \u0026 WHEELS": ["Tyres : 175/65R14", "Wheel Size : 14\" Steel(35.6)cms"],
"BRAKES": ["Front : Ventilated Discs", "Rear : Self Adjusting Drums "],
}, {
"INSTRUMENTATION": ["Tachometer : ", "Door Ajar Indicator : ", "Low Fuel Warning Lamp : ", "Distance To Empty (DTE) Display : ", "Headlamp on Key-off warning : "],
"TYRES \u0026 WHEELS": ["Tyres : 175/65R14", "Wheel Size : 14\" Alloy (35.6)cms"],
"BRAKES": ["Front : Ventilated Discs", "Rear : Self Adjusting Drums "],
}]
我有重复的INSTRUMENTATION，BRAKES，TYRES & WHEELS键。
我想创建一个不会重复键的单个对象，如果已存在相同的键，则会创建一个新的子数组对象。与INSTRUMENTATION，BRAKES和TYRES & WHEELS键一样，将创建一个新的数组对象。
除了jQuery，我不想使用任何第三方关键字。
预期结果应该是： -
[
{
"Steering": [
"Steering Type : EPAS with Pull Drift Compensation technology"
],
"Power & Performance": [
"1.5L Petrol Ti-VCT MT : ",
"1.5L Petrol Ti-VCT AT : ",

"1.5L Diesel DV5 MT : "
],

],
[
"Front : Ventilated Discs",

}
