In case you (or future readers) are still interested, it sounds like what you want here is GitHub - tc39/proposal-call-this: A proposal for a simple call-this operator in JavaScript. with the .. syntax option. For example:
function pipe(callback) { return callback(this); }
anything..pipe(x => x)
// String processing
"hello world "
.trim()
..pipe(str => `*${str}*`)
.toUpperCase()
// Array transformations
[1, 2, 3, 4, 5]
.filter(n => n > 2)
..pipe(arr => ({ sum: arr.reduce((a, b) => a + b, 0) }))
..pipe(({ sum }) => sum.toString())
.padStart(5, '0');
// Object manipulation
const user = { name: 'John', age: 30 }
..pipe(obj => ({ ...obj, role: 'admin' }))
..pipe(x => console.log(x) ?? x)
..pipe(({ role }) => role)
.toUpperCase();
No issues with null prototypes and doesnβt affect property access as in if (foo.pipe) bar().
