Object.assign() 没有按原样构造我的对象数组

Question

if (!this.favoriteCoins.some(e => e.cryptoName === coinId)) {

     Object.assign(this.favoriteCoins, {cryptoName: coinId})

}

The image is the result of my Object.assign and I wanted to know why doesn't it assign the way all the others are structured?

Answer 1

You are calling Object.assign and passing an array as an argument. Array's can still accept properties the same ways objects do. But if you want to add the object to the array, use Array.prototype.push instead.

if (!this.favoriteCoins.some(e => e.cryptoName === coinId)) {

     this.favoriteCoins.push({cryptoName: coinId})

}
