Beside above, how do you turn a string into an object in JavaScript? Use the JavaScript function JSON.parse() to convert text into a JavaScript object: var obj = JSON.parse('{ "name":"John", "age":30, "city":"New York"}'); Make sure the text is written in JSON format, or else you will get a syntax error.
Moreover, what is string in JavaScript?
A JavaScript string stores a series of characters like "John Doe". A string can be any text inside double or single quotes: var carName1 = "Volvo XC60"; var carName2 = 'Volvo XC60'; String indexes are zero-based: The first character is in position 0, the second in 1, and so on.
