On top of that, each segment in the mapping contains offsets rather than absolute indices, which means that you can't look at a segment in isolation – you have to understand the whole sourcemap.\n\nThis package makes the process slightly easier.\n\n\n## Installation\n\n```bash\nnpm install sourcemap-codec\n```\n\n\n## Usage\n\n```js\nimport { encode, decode } from 'sourcemap-codec';\n\nvar decoded = decode( ';EAEEA,EAAE,EAAC,CAAE;ECQY,UACC' );\n\nassert.deepEqual( decoded, [\n\t// the first line (of the
