When inputting the values {2,4,45,50} in the console, 50 is displayed. However, assigning these values to a variable results in an error:
var a = {2,4,45,50}
Uncaught SyntaxError: Unexpected number
Can you explain this concept?

When working with arrays, it's important to note that the console interprets curly braces {} as a block and returns the last value – skara9
As pointed out by Skara, use [] for arrays and {} for tables. When assigning values to a variable using {}, make sure to include key-value pairs, such as {a: 1, b:2, 3:4}. To work with arrays, replace {} with []. If you are dealing with tables, ensure each key has a corresponding value.
To access specific values in an array, use index numbers starting from 0. For instance:
var a = [2,4,45,50]
console.log(a[0])
//Expected output is 2If you prefer to work with a table and want to log the value of a particular key (e.g., a), follow this approach:
var test = {a:2, b:4, c:45, d:50}
console.log(test.a)
//Expected output is 2 as 'a' is associated with 2You can also choose to log the entire array or table if needed.
