Just use map and for
var myObj = [{ "name":"John", "age":30, "car":"maruti" },{ "name":"Smith", "age":50, "car":"indica" }];
var result = myObj.map(v=>{
v = Object.assign({}, v);
for( let k in v ) v[k] = "";
return v;
});
console.log( result );Changing the age only.
var myObj = [{ "name":"John", "age":30, "car":"maruti" },{ "name":"Smith", "age":50, "car":"indica" }];
var result = myObj.map(v=>{
v = Object.assign({}, v);
v.age = "";
return v;
});
console.log( result );10 Comments

What is the error? You have to check if it is working or not. Dont rely on you notepad/IDE. Your IDE might not be updated.
map is a new code, so i wast thinking your IDE is not updated.Mr.Prakash Mondal
My IDE version is IDE 8.0

Yes. it is successfully working in my browser (Mozila) that is: like abc.html <!DOCTYPE html> <html> <body> <p id="demo1"></p><br/> <br/><br/> <p id="demo2"></p> <script> var myObj, x; myObj = [{ "name":"John", "age":30, "car":"maruti" },{ "name":"Smith", "age":50, "car":"indica" }]; var result2= myObj.map(x => Object.keys(x).reduce((total, value) => { total[value] = ''; return total; }, {})); document.getElementById("demo2").innerHTML = JSON.stringify(result2); </script> </body> </html>

Is it working on Mozila when you put the code on .js?

Here's a solution that won't change the original value:
myObj.map(x => Object.keys(x).reduce((total, value) => { total[value] = ''; return total; }, {}));
