如果我有这样的数组,我该如何循环并将计数推入一个新数组?
欢迎所有帮助!
var Products = [
['Product A'],
['Product A'],
['Product A'],
['Product A'],
['Product A'],
['Product B'],
['Product B'],
['Product B'],
['Product B'],
['Product B'],
['Product B'],
['Product B'],
['Product B'],
['Product B'],
['Old Product B'],
['Old Product B'],
['Old Product B'],
['Old Product B'],
['Old Product B'],
['Old Product]
];
最终目标:
var UniqueProducts = [
['Product A',5],
['Product B',6],
['Old Product B',9]
];
