`Math.pow()` is a static method that returns a base raised to the power of the exponent (`value^exponent` operation).

``````// ONLINE-RUNNER:browser;

//                     base  exponent
console.log( Math.pow(  1  ,  2       ) ); // 1
console.log( Math.pow(  2  ,  2       ) ); // 4
console.log( Math.pow(  3  ,  2       ) ); // 9

console.log( Math.pow(  0  ,  3       ) ); // 0
console.log( Math.pow(  0.5,  0.3     ) ); // 0.8122523963562356
console.log( Math.pow( -1  ,  4       ) ); // 1

console.log( Math.pow(  0  , -0.4     ) ); // Infinity
console.log( Math.pow( -0.5, -2       ) ); // 4
console.log( Math.pow( -2.0, -2       ) ); // 0.25
console.log( Math.pow(  2.0 , 0.5     ) ); // 1.4142135623730951``````

## 1. Documentation

 Syntax `Math.pow(base, exponent)` Parameters The method takes integer or float number arguments (primitive values). `base` - base of power`exponent` - exponent used with a base Result `number` value (primitive value) calculated as base raised to the power of exponent or `NaN` if the operation can not be executed. Description `pow` is a static method that returns a base raised to the power of the exponent (`value^exponent` operation).

## 2. Exponentiation operator (`**`) example

``````// ONLINE-RUNNER:browser;

console.log(   1    **  2   ); // 1
console.log(   2    **  2   ); // 4
console.log(   3    **  2   ); // 9

console.log(   0    **  3   ); // 0
console.log(   0.5  **  0.3 ); // 0.8122523963562356
console.log( (-1)   **  4   ); // 1

console.log(   0    ** -0.4 ); // Infinity
console.log( (-0.5) ** -2   ); // 4
console.log( (-2.0) ** -2   ); // 0.25
console.log( (-2.0) **  0.5 ); // NaN``````

Note: this feature has been introduced in ES2016.
