How can I iterate objects in component of Angular 5

Question

I have object having string as keys and values. I want to trim all values of object in one go without need to check every index manually.

So, I have to iterate over object and will trim the value and the update value in object.

Can you share a way to iterate any object in Angulario 5.

let obj = {
  "name" => "    keshav     ",
  "prof" => "    Engineer   "
}

And I would like to this to convert into

let obj = {
  "name" => "keshav",
  "prof" => "Engineer"
}

This question is not Anguar(io5) specific. You must also show your attempts to resolve — Vega, May 11 '18 at 06:56

Object.entries(obj).forEach(([key, value]) => obj[key] = value.trim());

This way you maintain the reference of the object

you have to do like this, get all the object properties and then just trim it

 const properties = Object.keys(obj );
 properties.forEach(prop=>{
   obj[prop]= obj[prop].trim();  
 });

}
