// 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     ) ); // NaN
