Eval ():- JavaScript

November 13, 2019 - JavaScript

The eval() method is used to convert string to JavaScript expression, variable, statement, or sequence of statements.

If the argument is an expression, eval() evaluates the expression.

If the argument is one or more JavaScript statements, eval() executes the statements.

Code:-

<!DOCTYPE html>

<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
</head>
<body>
<h1>eval</h1>
<button onclick="getval();">Access eval</button>
<script>
/* Evaluate/Execute JavaScript code/expressions
Convert String to JavaScript expression, variable, statement, or sequence of statements. */
function getval()
{
var test = "a";
var a = "Anjali";
alert("test : " + test);
alert("eval(test) : " + eval(test));
}
</script>
</body>
</html>
