将数组中的每一个对象中相同属性值进行累加

let info=[
            {
    
     
                name:"小明",
                score:100
            },{
    
     
                naem:"小红",
                score:110
            },
            {
    
    
                name:"小强",
                score:120
            }
        ]
        
let totalScore=info.reduce((pre,cur)=>{
    
    
            return pre+cur.score
        },0)
 console.log(totalScore);//输出330
