How to use eval() with string replacement In Javascript
In this approach, we are using eval() with a string replacement (replace() method with /\\/g regular expression) to remove backslashes from the JSON string jStr, then evaluating the cleaned JSON string within parentheses using eval(). This produces a JavaScript object temp, which is stringified to generate the final result res, logging it to the console.
Syntax:
eval(expression)
Example: The below example uses eval() with string replacement to remove backslash from JSON string in JavaScript.
let jStr = '{\\"name\\": \\"Geek\\", \\"age\\": 22}';
let temp = eval(`(${jStr.replace(/\\/g, '')})`);
let res = JSON.stringify(temp);
console.log(res);
Output
{"name":"Geek","age":22}
