VisualizaçõesHow to use toLowerCase() function before filter?
I want to lowercase product.productName before filter, but I couldn't do that. I tried some thing but didn't work. Is there any way that I can lowercase product.productName before filter?

.map() could be used as a step before filter()
products
.map(product => product.productName.toLowerCase())
.filter(...)

Simply convert to lowercase inside filter before comparing.
e.g.
product.productName.toLowerCase().includes .....
If it complains about being an object, convert to string first.
product.productName.toString().toLowerCase().includes ....
