Lodash Clone Array vs Spread Operator

I was wondering if anyone knows whether the spread operator 

cosnt newArray = [...oldArray];

makes the lodash method

const newArray = _.clone(oldArray);

obsolete?

Or more importantly if either method is more efficient?

*Note this is a shallow clone, just want object references in a new array.

Thank you!

Solution

  • It looks like clone is faster than the spread operator: https://www.measurethat.net/Benchmarks/ShowResult/81691 .

    However, as javascript in an expensive resource to process, it's probably not a good idea to add a library to do what vanilla js can do perfectly well.
