Line debugging on JS trick

So, supposing you have the following code:

Object.entries({
apple: { pt: 'maça', color: 'red' },
lime: { pt: 'limão', color: 'green' },
})
.filter(([_key, value]) => value.color === 'red')
.map(([key, value]) => `${key} in Portuguese is ${value.pt}`)
.join(';\n ')

and you want to check the value of of the filtered array, you can do so using the comma operator, like so:

Object.entries({
apple: { pt: 'maça', color: 'red' },
lime: { pt: 'limão', color: 'green' },
})
.filter(([_key, value]) => value.color === 'red')
.map(([key, value], i, a) => (console.log(a), `${key} in Portuguese is ${value.pt}`))
.join(';\n ')

because the comma operator evaluates and executes the code on the left of the comma, but only returns the value on the right side of the comma, cheers :tada:.

I think that was a terrible example, but we will roll with it for now. Just so you know, this work anywhere, so use your creativity.
