使用ES6：

const updatedProducts = products.map(({text: label, value})=>({value, label}));

Answer 3

There are many ways using map in ES6



    var products = [
          { 
            text: 'prod1', 
            value: 1 
          },
          { 
            text: 'prod2', 
            value: 2 
          },
          { 
            text: 'prod3', 
            value: 3 
          }
     ];

    const newProducts = products.map(({text: label, value})=>({value, label}));
    console.log(newProducts );

    console.log("===================Another  Method====================")


    products.map((el)=>{
    el.label = el.text
    delete el.text
    })

    console.log(products);
