The code we want to trasform:

2 ** 3;a ** b;a **b * c;a ** b ** c;(a+1) ** (b+1);

 

transform to:

Math.pow(2, 3);Math.pow(a, b);Math.pow(a, b) * c;Math.pow(a, Math.pow(b, c));Math.pow(a+1, b+1);

 

Code:

export default function (babel) {  const { types: t } = babel;    return {    name: "ast-transform", // not required    visitor: {      BinaryExpression (path) {        console.log(t )        const isPowOpreator = path.node.operator === '**';        if(!isPowOpreator) {           return;        }                const {left, right} = path.node;        path.replaceWith(t.callExpression( // create Math.pow() node          t.memberExpression(            t.identifier('Math'),            t.identifier('pow')          ),          [left, right]  // pass in Math.pow(left, right)        ))      }    }  };}
