When to use an object or an array in javascript? [duplicate]

What is the main difference between { } and [ ] ?
I want to know when to use it and how stores the data
education: [
{
school: {
type: String,
required: true
},
fieldofstudy: {
type: String,
required: true
},
from: {
type: Date,
required: true
},
to: {
type: Date
},
current: {
type: Boolean,
default: false
},
description: {
type: String
}
}
]
social: {
youtube: {
type: String
},
twitter: {
type: String
},
facebook: {
type: String
},
linkedin: {
type: String
},
instagram: {
type: String
}
}
I would love to see some examples to understand where to use it and when not to use it.

Though the question likely illustrates a lack of understanding for JavaScript itself and the other references will help, then I would also suggest reading the MongoDB manual section on Data Modeling as a good place to start

{ } can contain index data (with string indexes), while [ ] can only contain unindexed data (which numerically indexed by default).
As your example suggests,
Here, data is on 0 index by default:
education: [{
school: {
type: String,
required: true
},
fieldofstudy: {
type: String,
required: true
},
from: {
type: Date,
required: true
},
to: {
type: Date
},
current: {
type: Boolean,
default: false
},
description: {
type: String
}
}]
Here data have string indexed
social: {
youtube: {
type: String
},
twitter: {
type: String
},
facebook: {
type: String
},
linkedin: {
type: String
},
instagram: {
type: String
}
}

while [ ] can only contain unindexed dataThis is unfortunately false. Arrays can contain pretty much the same sort of key-value pairs as objects, it's just an abuse of their structure to do so. Also, your code doesn't look great, strings require delimiters.
