I have a string in the form of an array. Like.., "["123", "456", "789"]"; "["abc", "xyz"]" I want to access the elements inside that is; "123", "456"... How can I do this in Javascript?

Here you go;
let str = "['123', '456', '789']"
let res = str.slice(str.indexOf('[') + 1, str.length - 1)
let result = res.split(', ')
let req = []
result.map(item => {
let i = item.replace(/'/g, '')
req.push(i)
})
console.log(req)Nothing special here. Used the in-built function slice to get the slice of the given string. Slice takes two args , starting index and end index. starting index character is included in the string, that is why, i am adding 1 to it to exclude '['. End index is excluded.
Then i splited the result at , , removed single quotes from every element. that is it.
