The function sum (k) {
Var kk=0; 
For (let n in k) 
Kk +=k [n]. 
Return kk. 
} 
Var obj={
A: 54.7. 
B: 99.8. 
C: 35.5 
}; 
The console. The log (sum (obj));

CodePudding user response:

Use 1/f,

 
The function sum (k) {
The return Object. Values (k). Reduce ((sum, value)=& gt; {
Return the sum +=value; 
}, 0) 
} 
Var obj={
A: 54.7. 
B: 99.8. 
C: 35.5 
}; 
The console. The log (sum (obj));
