Tengo una matriz de cadenas, que quiero comparar con una cadena de texto, si encuentra similitudes, quiero poder marcar en negro la similitud encontrada dentro de la cadena.

ejemplo:

 context.body: 'G-22-6-04136 - PatientName1' newBody: ['G-22-6-04136 - PatientName1' , 'G-22-6-04137 - PatientName2']

Al encontrar la similitud entre los dos, el resultado sería algo como esto

 newBody: [**'G-22-6-04136 - PatientName1'** , 'G-22-6-04137 - PatientName2']

¿Cómo podría hacerlo? ¿Es posible hacer esto? De antemano muchas gracias por la ayuda

 const totalSize: number = this.getSizeFromAttachments(attachments); const chunkSplit = Math.floor(isNaN(totalSize) ? 1 : totalSize / this.LIMIT_ATTACHMENTS) + 1; const attachmentsChunk: any[][] = _.chunk(attachments, chunkSplit); if ((totalSize > this.LIMIT_ATTACHMENTS) && attachmentsChunk?.length >= 1) { const result = attachment.map(element => this.getCantidad.find(y => element.content === y.content)) const aux = this.namePatient const ans = [] result.forEach(ele => { const expected_key = ele["correlative_soli"]; if (aux[expected_key]) { const newItem = { ...ele }; newItem["name_Patient"] = aux[expected_key] newItem["fileName"] = `${expected_key}${aux[expected_key] ? ' - ' + aux[expected_key] : null}\n`.replace(/\n/g, '<br />') ans.push(newItem) } }); let newBody: any; const resultFilter = attachment.map(element => element.content); const newArr = []; ans.filter(element => { if (resultFilter.includes(element.content)) { newArr.push({ fileNameC: element.fileName }) } }) newBody = `• ${newArr.map(element => element.fileNameC)}`; const date = this.cleanDateSolic; const amoung= attachmentsChunk?.length; const getCurrent = `(${index}/${attachmentsChunk?.length})` const header = `${this.cleanDateSolic} pront ${attachmentsChunk?.length} mail. This is the (${index}/${attachmentsChunk?.length})`; console.log('body', context.body); // context.body is the body I receive of frontend like a string const newContext = { newDate: date, amoung: amoung, getCurrent: getCurrent, newBody: newBody, ...context } return this.prepareEmail({ to: to, subject: ` ${subject} (Correo ${index}/${attachmentsChunk?.length})`, template: template, context: newContext, }, attachment); }
