如何仅将真值推送到空数组

Question

I have variables assigned to values as:

let x = 5;
let y = 17;
let z = 0;

const newArr = [];

Here I am trying to push the x, y, x values if they aren't falsy values

I am doing as:

if(x){
  newArr.push(x);
}
if(y){
  newArr.push(y);
}
if(z){
  newArr.push(z);
}

May I know more efficient way to do this, TIA

You might put all the variables into another array, then filter that array:

 let x = 5; let y = 17; let z = 0; const newArr = [x, y, z].filter(Boolean); console.log(newArr);
