How to remove falsy values (false, 0, "", null, NaN, undefined) from an object in TypeScript

Answer 1

const obj = {
  a: undefined,
  b: null,
  c: 'typescript',
  d: NaN,
  e: 74398,
  f: false,
  g: true,
  h: 'c++'
};

Object.keys(obj).forEach(key => {
    if (!obj[key]) {
        delete obj[key];
    }
});

console.log(obj);

 
   
     
     
/*
run:
     
{
  "c": "typescript",
  "e": 74398,
  "g": true,
  "h": "c++"
} 
     
*/
