¿Cómo puedo calcular la parte en porcentaje para cada usuario que usa loop for?

Tengo dos matrices aquí. Uno de proyectos y otro de plomo. Cada proyecto tiene idLead como clave externa. Ya he creado algunas funciones y están funcionando bien. Ahora solo quiero hacer un bucle en el prospecto para conocer la parte de cada prospecto en los proyectos. Quiero decir, ¿cuántos proyectos tiene cada cliente potencial en %?

 ngOnInit(): void { // This is intentional this.SumOfLead(); this.SumOfProjet(); this.ProjetParAnnee('2020'); this.leadParAnnee(); this.LeadProjetSum('2'); }
 leadList: any = [ { id: '1', libelle: 'Vector', anneeCreation: '2020' }, { id: '2', libelle: 'Salim', anneeCreation: '2021' }, { id: '3', libelle: 'Antoine', anneeCreation: '2020' }, { id: '4', libelle: 'Eya', anneeCreation: '2022' }, { id: '5', libelle: 'Juliette', anneeCreation: '2021' }, { id: '6', libelle: 'Anna', anneeCreation: '2021' }, ]; projetList: any = [ { id: '1', libelle: 'EcoleVector', anneeCreation: '2021', idLead: '1', }, { id: '2', libelle: 'Aramex', anneeCreation: '2021', idLead: '2' }, { id: '3', libelle: 'SpeedFood', anneeCreation: '2021', idLead: '4' }, { id: '4', libelle: 'Jumia', anneeCreation: '2022', idLead: '1' }, { id: '5', libelle: 'Amazon', anneeCreation: '2020', idLead: '5' }, { id: '6', libelle: 'AliBaba', anneeCreation: '2022', idLead: '6' }, { id: '7', libelle: 'TikTok', anneeCreation: '2021', idLead: '3' }, { id: '8', libelle: 'Teskerti', anneeCreation: '2022', idLead: '2' }, ];
 SumOfLead() { let nombreLead = this.leadList.length; console.log(nombreLead, 'nombre de leads'); } SumOfProjet() { let nombreProjet = this.projetList.length; console.log(nombreProjet, 'nombre de projets'); } ProjetParAnnee(annee: string) { let filteredProjet = this.projetList.filter( (list: any) => list.anneeCreation === annee ); console.log(filteredProjet, 'projets crées en 2020'); } leadParAnnee() { let annee = '2021'; let filteredLead = this.leadList.filter( (lead: any) => lead.anneeCreation === annee ); console.log(filteredLead, ' nombre de lead crées en 2021'); } LeadProjetSum(id: any) { let nombreProjet = this.projetList.length; let SumProjetForOneLead = this.projetList.filter((sum: any) => sum.idLead === id); let part = (SumProjetForOneLead.length * 100) / nombreProjet; console.log( SumProjetForOneLead.length, 'nombre de projet par lead ', 'part=', part + '%' ); }

Mejor que crear una función y usarla en .html, agregue una nueva propiedad a LeadList:

 const count=this.projetList.length; this.leadList.forEach(x=>{ x.part=this.projetList.filter(y=>y.idLead==x.id).length/count*100.0 })

o puede crear una matriz countProjects

 const countProject=this.projetList.reduce((a,b)=>{ const el=a.find(x=>x.id==b.idLead); if (!el) a.push({id:b.idLead,count:1}) else el.count++ return a },[]) //and use this.leadList.forEach(x=>{ const counter=countProject.find(y=>y.id==x.id) x.part=counter?counter.count/count*100.0:0 })

gracias a todos lo hice, es solo un bucle fácil

 leadProjetSum() { const nombreProjet = this.projetList.length; for (let lead of this.leadList) { let SumProjetByLead = this.projetList.filter( (project: any) => project.idLead === lead.id ); const partlead = (SumProjetByLead.length * 100) / nombreProjet; console.log( lead.libelle, ':nombre de projets =', SumProjetByLead.length, ':part est =', partlead + '%' ); } }
