Question

I need to improve the performance of a script done in Javascript, and I can check the RAM consumption script said.

for example like the PHP function get_memory_get_peak()

Answer 1

In Chrome, if you run with the --enable-memory-info flag, you can get the data from:

console.memory;

which contains:

jsHeapSizeLimit
totalJSHeapSize
usedJSHeapSize

This data can also be fetched from a memory heap snapshot by pressing F12, but this is not programmatically.
