Why does my filter not work when i add intergers?
I try to show and hide elements from an array. The entire filter works well except with the numbers. When I use this filter that item.sprint === does not grab this.state.currentSprint and just displays both:
{ this.state.personalItems .filter( item => item.user == this.state.user || item.public == "true" && item.sprint === this.state.currentSprint ) .map((l, i) => ()) } This variable corresponds to 1 === 2 as in the following example:
{ this.state.personalItems .filter( item => item.user == this.state.user || item.public == "true" && 1 === 2 ) .map((l, i) => ()) } I have already checked if they are integers etc. does anyone have the solution where it goes wrong?
Check operator precedence for && and ||. In your code it will evaluate condition as below.
item => item.user == this.state.user || (item.public == "true" && item.sprint === this.state.currentSprint) You should use wrap || condition with () and update condition as below.
{ this.state.personalItems .filter( item => (item.user == this.state.user || item.public == "true") && item.sprint === this.state.currentSprint ) .map((l, i) => ()) }
