How do I rewrite the JSON object in a file using file system in Node Js

I have came across the read and write operations using fs in Node Js.

My scenario is like, I have a file having the data like ,

[
{
    "Pref":"Freedom",
    "ID":"5545"
},
{
    "Pref":"Growth",
    "ID":"8946545"
}
]

I have to replace the Pref of the element whose ID is 5545 using Node js.

How can I do it. Thanks
