A developer wants to iterate through an array of objects and count the objects and count
the objects whose property value, name, starts with the letter N.
Const arrObj = [{“name” : “Zach”}, {“name” : “Kate”},{“name” : “Alise”},{“name” :
“Bob”},{“name” :
“Natham”},{“name” : “nathaniel”}
Refer to the code snippet below:
01 arrObj.reduce(( acc, curr) => {
02 //missing line 02
02 //missing line 03
04 ). 0);
Which missing lines 02 and 03 return the correct count?
- A . Const sum = curr.startsWith(‘N’)? 1: 0;
Return acc +sum
B. Const sum = curr.name.startsWith(‘N’)? 1: 0;
Return acc +sum
C. Const sum = curr.startsWIth(‘N’)? 1: 0;
Return curr+ sum
D. Const sum = curr.name.startsWIth(‘N’)? 1: 0;
Return curr+ sum
Suggested Answer: B
