I need assistance with...
let a = ['a', 2, 3];
a += function(){return 'abc'};
console.log(a[3]);
Therefore, I am looking for a shorthand method to push() in array with the above content.
Does anyone know of an operator that can help achieve this?
Definitely not - besides, there is no issue with this:
let b = ['x', 'y', 'z'];
b.push('w');
In case you desire to push a result:
b.push((function() { return 'q'; })());
Adding value to an array using a.push(value)a[a.length] = value
From my understanding, operator overloading is not supported, hence this functionality is not available.
To transform your text into an array, simply utilize the .split() method:
'Hello'.split('');
Next, employ .concat() to combine the outcomes:
b = b.concat( 'Hello'.split() )
If preferred, you can encapsulate these actions within a function.
Unfortunately, in JavaScript, ES5 getter-setters can intercept assignments using the specified methods, but there is no built-in operator overloading mechanism to intercept and modify operations like + or +=.
One workaround could involve special handling for primitive values when adding them.
var appendable = {
x_: [1, 2],
get x() { return this.x_; },
set x(newx) { this.x_.push(newx.substring(("" + this.x_).length)); }
};
alert(appendable.x);
appendable.x += 3;
alert(appendable.x); // This will display 1,2,3 instead of 1,23
alert(appendable.x.length);
However, it's worth noting that using the .push method is generally recommended for appending elements to an array.
