JavaScript Operators Mocktest

Bitwise OR

<div>Multiplying a number by a non-numeric value in JavaScript results in NaN (Not a Number).</div>

<div>The code x += '2' is equivalent to x = x + '2', resulting in concatenation of the string '2' to the number 5, giving '72'.</div>

<div>When adding a string and a number in JavaScript, it concatenates the values as strings from left to right, resulting in '52'. Subtraction then occurs, converting '52' to a number, resulting in 52 - 1 = 51.</div>

<div>The code x += 5 is equivalent to x = x + 5, which results in x = 10 + 5 = 15. Then, x /= 3 is equivalent to x = x / 3, which results in x = 15 / 3 = 5.</div>

<div>When adding a string and a number in JavaScript, it concatenates the values as strings from left to right, resulting in '1010'.</div>

<div>When adding a number and a string in JavaScript, it concatenates the values as strings from left to right, resulting in '102'. Subtraction then occurs, converting '102' to a number, resulting in 102 - 1 = 101.</div>

<div>The code x -= 2 is equivalent to x = x - 2, which results in x = 10 - 2 = 8. Then, x *= 3 is equivalent to x = x * 3, which results in x = 8 * 3 = 24.</div>

<div>Subtracting a number from a string in JavaScript converts the string to a number, so '7' - 3 results in 4.</div>

<div>The unary operator + converts its operand to a number, so + '5' results in 5.</div>
